General Description

Optical system

With a choice of up to 6 excitation sources and 6 detection filters combined with a short, fixed optical path, the

Rotor-Gene Q can be used for multiplex reactions, ensuring minimum fluorescence variability between samples and eliminating the need for calibration or compensation.

Samples are excited from the bottom of the chamber by a light-emitting diode. Energy is transmitted through the thin walls at the base of the tube. Emitted fluorescence passes through emission filters on the side of the chamber and is then collected by a photomultiplier. The fixed optical path ensures consistent excitation for every sample, which means that there is no need to use a passive internal reference dye such as ROX.

4.9.2

Installation Procedures significant system resources and thus slow down the Rotor-

Gene Q software. It is particularly important to pay attention to the points listed below.

System administrators are advised to consider any impact that a modification to the system may have on the resources before implementing it.

Virus scanners

We are aware of the threat that viruses cause to any computer that exchanges data with other computers. Rotor-

Gene software is primarily installed in environments where local policies exist to minimize this threat. These policies usually require use of a particular anti-virus tool. Due to the sheer number of anti-virus tools available, it is not possible for QIAGEN to predict the possible impact on the Rotor-

Gene Q software if such a tool is active during a PCR run. In order to get consistent results, system administrators should therefore ensure that during performance of a PCR run:

File access is not intercepted by a virus scanner

Updates to the virus database are not performed

File scans are not performed

We strongly recommend disabling virus scanner activity during real-time PCR data acquisition. The critical virus scanner tasks described above can only be safely carried out without running the risk of impacting the performance of the instrument when the Rotor-Gene Q software is not running.

Otherwise there is a risk of adverse impact on the performance of the instrument.

System tools

Many system tools may use significant system resources even without any user interaction. Typical examples of such tools are:

File indexing, which is performed as a background task by many contemporary office applications

Disk defragmentation, which often also employs a background task

Any software that checks for updates on the internet

Remote monitoring and management tools

Please be aware that due to the dynamic nature of the IT world, this list may not be complete and tools may be released that are not known at the time of writing. It is important that system administrators take care that such a tool is not active during a PCR run.

Operating system updates

We strongly recommend turning off any automatic update processes of the operating system on the computer that is used for data acquisition on the Rotor-Gene Q. We are closely monitoring available updates and will notify customers whenever an update is considered to be safe and important to be installed.

Updating software

Software updates are available from the QIAGEN Web site at www.qiagen.com/RotorGeneQ. Online registration is necessary to download the software.

Rotor types

First, select which tube type and rotor to use. There are 4 rotors available to accommodate different tube types.

Note: 36-Well Rotor and 72-Well Rotor are delivered with the instrument. The Rotor-Disc Rotors are accessories.

IMPORTANT: Use identical tubes in a run. Do not mix different tube types or tubes from different manufacturers, as this will affect optical uniformity. We recommend use of tubes from QIAGEN which are specially designed for use with the

Rotor-Gene Q (see Appendix E). Tubes from alternative

manufacturers may autofluoresce, which could affect the reliability of results. In addition, tubes from alternative manufacturers can vary in length and thickness, resulting in misalignment of the optical path of the Rotor-Gene Q and the reaction in the tube. QIAGEN reserves the right to refuse technical support for problems induced by non QIAGEN certified plastic materials on the Rotor-Gene Q instrument.

Rotor-Disc 100 Rotor

The Rotor-Disc 100 Rotor is gold in color. The Rotor-Disc

100 Rotor and Rotor-Disc 100 Locking Ring enable use of the Rotor-Disc 100. The Rotor-Disc 100 is a disc with 100 wells for high-throughput use. The Rotor-Disc 100 is the rotary equivalent of a 96-well plate but with an additional 4 reference wells. It enables integration of the Rotor-Gene Q with 96-well laboratory workflows. The extra wells can be conveniently used for more samples, additional control reactions, or orientation reactions, without occupying any of the standard 96-well positions. For seamless 96-well workflow compatibility, Rotor-Disc 100 wells use 96-well plate labeling conventions, i.e., A1–A12 through to H1–H12.

The additional 4 reference wells are labeled R1–R4. For

The acquisition options described above also apply to “Melt” steps, except that it is not possible to append acquisition data using the “Same as Previous” menu.

Melt and hybridisation

A Melt is a ramp between 2 temperatures, from a lower to a higher temperature. The permitted temperature range is

35–99ºC.

To set up a Melt, specify the start temperature, the end temperature, the temperature increments, the length of time to hold at the first acquisition temperature before the ramp is initiated, the time each increment is to be held for, and the acquisition channels.

A ramp will be generated between the 2 temperatures. If the start temperature is higher than the end temperature, the name of the step will change to “Hybridisation”. The

“Acquiring To” option, set to Melt A in the screenshot below, can be changed by clicking the button. The “Acquisition” window will appear and the channels can be selected.

Rotor-Gene Q User Manual 02/2012 6-17

Operating Procedures — Software

6-18

When running a standard melt the temperature is increased by increments of 1ºC, waiting for 5 seconds before each acquisition. The Rotor-Gene Q can be configured to perform melts in 0.02ºC increments. The minimum hold time between temperature steps varies depending on the number of degrees between each step.

High Resolution Melt

High resolution melt (HRM) analysis characterizes doublestranded DNA samples based on their dissociation (melting) behavior. It is similar to classical melting curve analysis, but provides far more information for a wider range of applications. Samples can be discriminated according to sequence, length, GC content, or strand complementarity, down to single base-pair changes.

HRM analysis can only be performed on instruments that have HRM hardware and software installed. Data is acquired using specialized HRM sources and detectors. HRM analysis also includes the option to perform Gain Optimisation just before the Melt begins. After performing HRM, the data can

be analyzed with HRM analysis software (Section 11).

Optical Denature Cycling

Optical Denature Cycling is an exciting technique, available on the Rotor-Gene Q, which performs real-time melt analysis to determine the melt peak of a reference sample. This indicates PCR product denaturation with higher precision than setting a particular denature temperature for a hold time. To perform this technique, simply place a reference tube of PCR product in tube position 1 of the rotor. The

Rotor-Gene Q User Manual 02/2012

Operating Procedures — Software reference tube must also contain a detection chemistry that enables detection of strand dissociation.

When heating to the initial denature temperature, a melt is performed on the green channel from 80ºC to 95ºC, by default. The parameters of this initial melt can be adjusted by the user. From this data, a melt curve is generated and automatically analyzed.

The melt peak is referenced back to the raw data to obtain a denature threshold. Then, every Optical Denature Cycling step, the instrument is heated as quickly as possible and data is acquired continually. Once the reference tube has reached the denature threshold fluorescence level, the instrument is immediately cooled and proceeds to the next programmed step in the cycle. A peak is not calculated while cycling.

Instead, the fluorescence level is referenced to the melt peak and this designates the denature threshold.

In the following graph, the raw fluorescence readings and the first derivative have been overlaid. This shows the correspondence between the denature threshold and the melt peak obtained during the calibration.

Rotor-Gene Q User Manual 02/2012 6-19

Operating Procedures — Software

6-20

To perform Optical Denature Cycling, you will need:

A preamplified PCR product to place in position 1 of the rotor. This sample should contain the same PCR product as the samples of interest and a detection chemistry for monitoring PCR product dissociation.

An optical denature profile. A new profile can be created or an existing profile can be edited (see details below).

An Optical Denature Cycle appears almost identical to other cycles. The principal differences are the melt step automatically inserted at the beginning of the profile, and the sharp profile of the denature step during cycling. The Optical

Denature Cycle does not require defined hold times as the dissociation of the product is monitored at each cycle.

To perform this technique, the following information about the run is required:

The initial denaturation temperature. This is the same temperature as the Denature step in a standard cycling profile.

The tube position of the PCR sample that will produce a melt curve on the green channel.

An Optical Denature Cycling profile must be defined.

Create a new Optical Denature Cycle as follows.

1. Open the “Edit Profile” window. Then click on “New”. In the window that appears, click the “Insert after” button

Rotor-Gene Q User Manual 02/2012

Operating Procedures — Software and select “New Cycling” from the menu. Select one of the temperature steps by clicking on the graph. In the drop-down menu, change from “Timed Step” to “Optical

Denature”. A default profile containing a Denature step and an Optical Denature Cycle step will appear.

The ramped region at the beginning of the run represents the calibration process. The green dots represent the acquisitions taken each cycle during heating. The blue dots represent the acquisition at the end of the anneal step at 60ºC. Note that while the profile shows each step with the same denature temperature, this may not be the case. If the sample requires slightly longer to melt towards the end of the run, the optical denature process waits for the melt according to the fluorescent data, and not according to time. For this reason, the temperature trace may vary for each cycle.

2. Click on the first half of the graph with the Optical

Denature symbol . The “Calibration Settings” information appears on the left of the screen.

3. The “Calibration Settings” information is usually correct.

To modify it, if necessary, click “Edit”. The “Calibration

Operating Procedures — Software

4. Ensure that:

The tube indicated in “Tube Position” contains a PCR product that will show a melt peak on the green channel.

The final ramp temperature will not burn the sample, yet will be high enough to allow it to melt.

The hold time is sufficient to denature the sample.

The denature offset is set appropriately. The default of 0 o C is appropriate for most melts. Melts with very sharp transitions may require a denature offset of

–0.5

o C to –2 o C, as determined by the user, to ensure that melt transition is detected.

You can also define a Denature step by introducing a new

Hold step. Click on “Insert before” and select “New Hold at

Temperature” from the menu. The calibration settings will appear.

6-22 Rotor-Gene Q User Manual 02/2012

Operating Procedures — Software

The calibration settings are synchronized with the denature settings, so a change to the hold time in the Denature step will automatically update the calibration hold time. This is because the calibration process and denaturation are equivalent in Optical Denature Cycling.

Gain Optimisation

When setting up a new run, it is helpful to use the “Gain

Optimisation” function. This allows you to optimize the gain to a setting that will provide the desired range of starting fluorescence at a set temperature (usually the temperature at which data acquisition occurs) in each of the channels being acquired. The aim of Gain Optimisation is to ensure that all data is collected within the dynamic range of the detector. If the gain is too low, the signal will be lost in background noise. If it is too high, all signal will be lost off scale

(saturated).

The gain range for each channel is –10 to 10, where –10 is the least sensitive and 10 is the most sensitive.

When running reactions for the first time, we recommend preparing a test sample containing all the reaction components. Place the test sample in the Rotor-Gene Q and use Gain Optimisation to determine the best gain setting. If the gain chosen by Gain Optimisation results in a poor signal then the “Target Sample Range” should be increased.

If it results in a signal that is saturated then the “Target

Sample Range” should be decreased.

To perform Gain Optimisation, click on the ”Gain

Optimisation…” button in New Run Wizard window 3 (see

The cycles before the change are excluded from the analysis.

Note: Gain Optimisation may chose a setting which does not fall within the specified range. This can be due to changes in fluorescence after the first Hold step. However, the result of Gain Optimisation provides a good indication of the fluorescence level the run will be started on.

Manual Gain Adjustment

To perform “Manual Gain Adjustment”, click on “Manual…” in the “Auto-Gain Optimisation Setup” window. The “Manual

Gain Adjustment” window appears. This window displays the fluorescent readings at any given temperature in real-time. It is used when the background of a sample is unknown and therefore the gain must be determined to ensure the sample signal is sufficient for detection.

By default, all samples are shown in the display. Samples can be removed from or added to the display using the toggler to the right. The toggler consists of colored cells, each of which corresponds to a sample in the display.

Samples with a brightly colored cell are displayed, while samples with a faded cell are not displayed. Samples can be switched on or off by clicking on the cell or by dragging the mouse pointer across several cells at time.

We recommend performing Manual Gain Adjustment as follows.

1. Adjust the temperature in the “Manual Gain Adjustment” window to the acquisition temperature required for the run.

Rotor-Gene Q User Manual 02/2012 6-29

Operating Procedures — Software

Note: The temperature will not be adjusted while the

Rotor-Gene Q is operating. Restart the Rotor-Gene Q to apply changes made to the temperature.

2. Click on “Start”. The run begins. The Rotor-Gene Q temperature is adjusted to the temperature specified in the window. The graphs in the window start to display data.

3. Wait for the temperature to stabilize.

4. Note the end point fluorescence (Fl) reading.

5. If the Fl reading is not at the required level, click on “Edit

Gains…” and edit as required. This process may not be instantaneous, as the Rotor-Gene Q takes ~4 seconds to acquire each point in each channel, and during this time the user interface is deactivated.

6. Repeat the process until the FI is at the desired level.

7. Click on “Stop”. If the run is still acquiring data when the

“Stop” button is clicked, the Rotor-Gene Q finishes acquiring first, and then stops. This process can take up to 5 seconds for each acquiring channel.

Analysis User Interface

Crop start cycles: This creates a new channel data set in which some start cycles have been removed. This is useful if large jumps are observed in the initial cycles, which can occur when using certain chemistries.

Crop end cycles: This creates a new channel data set in which some end cycles have been removed.

Page 1: This indicates the page that is currently selected to display the raw data plots. The

“Edit Sample” window allows the creation of multiple sample definitions. For example, data can be viewed with varying line thickness, sample definitions, and other display options. This is particularly useful if relative quantitation is performed in a single channel, because the user can easily switch the view between the gene of interest and housekeeper samples by defining 2 sample pages.

Toggling samples

At the right-hand side of the main window is a toggler, which includes a sample legend. This consists of colored cells, each of which corresponds to a sample in the display. The toggler is used to control which samples can be seen in the display.

Samples with a brightly colored cell are displayed while samples with a faded cell are not displayed. Samples can be switched on or off by clicking on the cell or by dragging the mouse pointer across several cells at time. The “Bank On” and “Bank Off” buttons hide or display, respectively, all samples currently visible in the list. The scroll bar can be used to display the next group of samples.

Note: The number of displayed samples is dynamic, and depends on the space available in the window.

Efficiency:

The values on the standard curve are recalculated dynamically as the threshold level is varied by clicking and dragging the threshold line in the main window.

Blue dots on the curve represent the samples that have been defined as standards and red dots represent the unknown sample data points.

Note: If redefining standards to recalculate the standard curve, toggling the standard sample visibility to off using the toggler on the right of the screen will remove it from the standard curve calculation. Removing standards from the graph to increase the

R^2 value is not scientifically valid. A failed standard is an indication that the samples may also have failed, and so should be included in the results.

This is the reaction efficiency of the run.

This value is discussed in more detail on

page 7-28.

Rotor-Gene Q User Manual 02/2012

Analysis User Interface

R^2 value

(correlation coefficient):

The R^2 value, or R 2 value is the percentage of the data that is consistent with the hypothesis that the standards form a standard curve. If the R 2 value is low, then the standards do not easily fit onto a line of best fit. This means that the results

(i.e., the calculated concentrations) may not be reliable. A good R approximately 0.99.

2 value is

Note: It is possible to achieve a high R^2 value with a poor standard curve if an insufficient number of standards have been run. The R^2 value improves as the number of standards decreases. For a more accurate indication of the reliability of the results, use the confidence intervals on the calculated concentrations as a guide.

R value (square root of correlation coefficient):

The R value is the square root of the R^2 value. In general, the R^2 value is more useful for determining correlation.

M and B:

Export Graph...: Clicking the right mouse button over the standard curve displays the option to export

the graph (see Section 8.4).

Overlay:

The slope (M) and the intercept (B) of the standard curve are automatically calculated using the formula y = Mx + B, and shown in the “Standard Curve” window.

When multiple quantitation runs have been performed in the same run, it is possible to overlay the standard curves in the same window. This is useful for graphically viewing the difference between different thresholds. This feature is shown in the screenshot below.

Analysis User Interface between 2 runs. Curves can be imported from another channel or from another run by clicking on “Import Curve”.

It is possible to adjust the standard curve, if required.

Adjusting the standard curve means that only the efficiency of the source standard curve is imported into the current run.

Whether or not the standard curve should be adjusted depends on the chemistry used.

To adjust the standard curve, use a reference in the new run with a known concentration. Define a reference by setting the sample type to “Standard” and entering a concentration value in the “Edit Samples” window. Multiple copies of the same reference can be entered to improve accuracy. Note that it is not possible to define more than one reference concentration or standard. For example, it is possible to have

3 replicate references of 1000 copies, but it is not possible to have one reference of 1000 copies and another with 100 copies in the same run.

Once the standard curve has been imported, the standard curve type changes to “Fixed”. Click “Reset” to change the standard curve type back to “Floating”.

T

Threshold: To set the threshold, click on the icon (a grid with a red arrow) then click and hold on the graph and drag the line to the desired level. Alternatively, enter a log value. Alternatively, “Auto-Find Threshold” can be used to automatically determine the threshold. When setting a threshold manually, it should be set in the exponential phase of the run, significantly above the background level to avoid noise and below the onset of signal plateau in later cycles.

Eliminate Cycles before:

To set, click on the icon (a grid with a red arrow) then click and hold on the graph and drag the line to the right. This eliminates the threshold for low cycle numbers.

Note: This is useful when there is noise during the initial cycles, for example, due to sample mixing effects.

Threshold:

This function scans the selected region of the graph to find a threshold setting which delivers optimal estimates of given concentrations. The selected region can be changed by entering new upper and lower bounds in the text boxes which appear.

For most analyses, the default upper and lower bounds are suitable. The range of threshold levels is scanned to obtain the best fit of the standard curve based on the samples that have been defined as standards (i.e., where the R value is closest to 1.0).

95% C.I.:

A range of concentrations that accounts for

95% of the variation in the individual sample as well as the linear regression model on which it is based. An interpretation of this measure is that it is the range of concentrations that could be expected 95% of the time if this run were performed repeatedly with the same amount of variation. This is a conservative estimate, and the range can be quite large due to the variation inherent in any realtime analysis. This range can be large if standards are run with concentrations different from the unknown samples, if a small number of replicates are used, or if there is significant variation.

IMPORTANT: The variations reported by this measure are inherent to the exponential process of real-time amplification and are not due to the

Rotor-Gene Q. Similar tests performed on block-based cyclers would yield greater variation due to the lower temperature uniformity of block-based systems. To compare cyclers if desired, we recommend comparing the standard deviation of the C value.

7-24 Rotor-Gene Q User Manual 02/2012

Analysis User Interface

In this screenshot, the concentrations of several samples are analyzed.

IMPORTANT: The “AutoStat” feature is context-aware. This means that, where possible, it only generates information that is useful.

For example:

It is not possible to obtain a 95% confidence interval from a set of selected calculated concentrations because the regression model must also be taken into account.

The "Orders of Magnitude" standard deviation is reported for calculated concentrations rather than an absolute value. This is a percentage variation. For example, a value of 1.07537 represents a 7.54% variation (278,974 – 322,611)=(300,000/1.07537 –

300,000*1.07537). Reporting an absolute value does not make sense for a standard curve. The value could be reported at the lowest concentration to create a perceived low error (± 3 copies) or at the high concentration (± 3,000,000 copies). For this reason, the

“Orders of Magnitude” standard deviation is reported.

For calculated concentrations, the geometric mean is used instead of the arithmetic mean. This accounts for the exponential nature of real-time PCR. For example, in the case of twofold dilutions with 1, 2, 8, and 16 copies, the average should be 4 copies, because it is the middle of the dilution series. However the arithmetic mean is

6.75. The geometric mean is (1*2*8*16)^(1/4)=4 copies.

Rotor-Gene Q User Manual 02/2012 7-25

Analysis User Interface

Dynamic tube normalization

The “Dynamic Tube” option is selected by default and is used to determine the average background of each sample just before amplification commences.

Standard normalization simply takes the first 5 cycles and uses these as an indicator of the background level of each sample. All data points for the sample are then divided by this value to normalize the data. This can be inaccurate because for some samples the background level over the first

5 cycles may not be indicative of the background level just prior to amplification. In contrast, dynamic tube normalization uses the second derivative of each sample trace to determine a takeoff point for each sample. The background level is then averaged from cycle 1 up to this takeoff cycle number for each sample. This gives the most precise quantitation results.

Note that for some data sets, background fluorescence is not consistent during the cycles before amplification commences.

In these cases, it may be necessary to deselect dynamic tube normalization by clicking on “Dynamic Tube” because it could result in less precise quantitation.

Noise slope correction

The background fluorescence (Fl) of a sample should ideally remain constant before amplification. However, sometimes the Fl shows a gradual increase or decrease over several cycles due to the chemistry used. This produces a skewed noise level. Noise slope correction uses a line-of-best-fit to determine the noise level instead of an average and normalizes to that line. Selecting this option by clicking the

“Slope Correct” button can improve data from replicates if sample baselines are noticeably sloped. Noise slope correction improves the data when raw data backgrounds are observed to slope upward or downward before the takeoff point (C

T

).

7-26 Rotor-Gene Q User Manual 02/2012

Analysis User Interface

Ignore First

The fluorescence signal from the first few cycles in a run may not be representative of the rest of the run. For this reason, better results may be achieved if the first few cycles are ignored. However, if the first cycles look similar to subsequent cycles, better results will be achieved by deselecting “Ignore First” because the normalization algorithm will have more data to work with.

Outlier Removal

To distinguish between minor changes in fluorescence and genuine reactions in no template controls (NTCs), 2 measures are provided: “NTC Threshold” and “Reaction

Efficiency Threshold”. The “NTC Threshold” is recommended for most applications. The approach used should be validated.

Rotor-Gene Q User Manual 02/2012 7-27

Analysis User Interface

NTC Threshold: This allows samples or NTCs that have a slight drift upwards to be excluded from analysis. All samples with a change below the “NTC Threshold” will not be reported and a flag “NEG (NTC)” will be shown in the “CT Comment” column.

The percentage is relative to the largest maximum change found in any tube. For example, if one sample began at a background of 2 Fl and increased to 47 Fl, then 45 Fl represents 100%. An “NTC

Threshold” of 10% would consider any sample less than 4.5 Fl as noise.

Reaction

Efficiency

Threshold:

The “Reaction Efficiency Threshold” is an alternative method of excluding noise from analysis. This normalizing algorithm uses the reaction efficiency estimation techniques used in comparative

quantitation (see Section 7.6.6). All

samples that do not have a reaction efficiency of at least this level are excluded and a flag “NEG (R.Eff)” will be shown in the “CT Comment” column.

A level of 0% indicates that, during the exponential phase, no reaction took place.

100% indicates that a completely efficient reaction took place during the exponential phase. Negative percentages indicate that during the exponential phase, the fluorescent signal declined.

Current research is not conclusive on the precise levels of efficiency needed to distinguish genuine reactions from contamination and other effects. For this reason, we recommend using this feature conservatively, with the assumption that any sample with a genuine reaction will have some visible exponential phase with

7-28 Rotor-Gene Q User Manual 02/2012

Analysis User Interface some increase in fluorescence. Setting this value higher than 0% will exclude some samples with inefficient, but perceptible increase in fluorescence, whereas setting below 0% will display samples that decreased in fluorescence during the exponential phase, which should clearly be excluded.

Note: If a value is excluded due to activation of either of these techniques, a corresponding C

T

value in the

“Quantitation Results” window will not be displayed.

Simultaneously, a flag indicating the exclusion will be shown in the “Ct Comment” column. It is therefore important to make sure that the “Ct Comment” column is displayed at all times.

In the image below, samples 7, 8, and 9 were excluded due to the “Reaction Efficiency Threshold”.

Slope, amplification, reaction efficiency

The slope (M) of a reaction (shown in the “Standard Curve” window), can be used to determine the exponential amplification and efficiency of a reaction using the following calculations:

Exponential amplification = 10 (–1/M)

Reaction efficiency = [10 (–1/M) ] – 1

Optimal values for M, exponential amplification, and reaction efficiency are –3.322, 2, and 1, respectively. The reaction efficiency is displayed in the report (in full and

Rotor-Gene Q User Manual 02/2012 7-29

Analysis User Interface

standard reports, see page 7-13) and in the “Standard

Curve” window.

The slope is calculated as the change in C

T

divided by the change in log input (e.g., copy number). A 100% efficient amplification means a doubling of amplification product in each cycle resulting in an M value of –3.322, an amplification factor of 2, and a reaction efficiency of 1.

Given an M value of –3.322, the calculations are as follows:

Exponential amplification: 10 (–1/–3.322) = 2

Reaction efficiency: [10 (–1/–3.322) ] – 1 = 1

As an alternative example: an M value of 3.8 means that the reaction has an exponential amplification of approximately

1.83 and a reaction efficiency of 0.83 (or 83%).

Offset

In a formula describing the relationship between 2 variables, the offset is expressed with the letter B (y = Mx + B). The offset is also sometimes referred to as the intercept.

B represents the C

T

for a given concentration of 1 unit. By substituting 1 into the concentration formula as shown below:

C

T

= log(1) * M + B

C

T

= 0 * M + B

The result is C

T

= B

The intercept can change from run to run and is a less stable measurement than the gradient. For this reason, the gradient is analyzed more frequently than the intercept.

Main window

The main window displays the amplification plots on a log scale.

Clicking “Linear Scale” at the bottom of the window changes the scale from the log scale to the linear scale and vice versa. Changing between these scales only alters the display of the graphs, not the calculations. This can be verified by

Quantitation analysis templates allow the user to export normalization and threshold settings into a single *.qut file.

This file can be imported and reapplied in other experiments.

See Section 8.1 for more details.

7.6.3 Two standard curve

Relative gene expression analysis using a normalizing gene can be performed using the 2 standard curve method.

The method requires a standard curve for each gene. The concentration for each gene is quantified according to its standard curve. The expression of the gene of interest is then normalized with the normalizing gene (often a housekeeping gene).

It is important that the standards and replicate samples are

designated correctly during sample setup (see Section 6.1.4).

In particular, corresponding samples must have the same name in each analysis. In a multiplex reaction, where the tube positions of the gene of interest and the normalizing gene are the same, one set of sample definitions is sufficient.

If performing relative analysis with a normalizing gene using a single channel (i.e., reactions are run in separate tubes

Rotor-Gene Q User Manual 02/2012 7-31

Analysis User Interface using the same fluorophore), then 2 sample pages should be created. The first should label the tube positions with sample names for the gene of interest, with the other positions left unnamed. The second should label the positions used for the normalizing gene. The software will then match samples across the 2 analyses based on their names.

Expression analysis using the two standard curve method

Data can first be analyzed for each gene using quantitation analysis. Otherwise, the results for each gene will automatically be determined using the “Autofind Threshold” tool.

1. From the “Analysis” window, select the “2 Std Curve

Repeat the procedure for the normalizing gene.

Optionally, a calibrator can be defined. If this option is selected, the calibrator is assigned a value of 1 and all other sample concentrations are calculated relative to this sample.

method enables relative gene expression

analysis. It is described by Livak and Schmittgen (2001)*.

This method does not require standard curves to be included in each run. Each sample is first normalized for the amount

These normalized values are further normalized relative to a calibrator treatment. The calibrator could be, for example, wild-type, untreated control, or time-zero samples.

7.6.5 Melt curve analysis

Melt curve analysis analyzes the derivative of the raw data after smoothing. This analysis is commonly used for genotyping and allelic discrimination. Peaks in the curve are grouped into bins, and all peaks below the threshold are discarded. Bins can then be mapped to genotypes using the

“Genotypes” command.

Rotor-Gene Q User Manual 02/2012 7-39

Analysis User Interface

After a run has finished, for some chemistries a melt step can be added to visualize the dissociation kinetics of the amplified products. The temperature is increased at a linear rate and the fluorescence of each sample is recorded. A typical melt curve analysis is shown below.

7-40 Rotor-Gene Q User Manual 02/2012

Analysis User Interface

Flip sign of dF/dT:

Defining peaks: In melt curve analysis, peaks can be defined and reported using different methods. One is to automatically call all the peaks for each sample. The other is to assign peaks to bins, which is useful for genotyping.

Bins define the area where peaks are expected to occur. The melt curve analysis software clusters peaks into bin groups, based on actual peak values in the curve.

Bins can be edited if required.

Any peak that is within the defined range of the bin will be assigned to the bin. If there are 2 bins close together then the peak will be assigned to the closest bin.

Note: The bins should not be visually positioned to estimate peak positions. Set the bins in the approximate area of interest, then use the actual reported values in the results table for a more accurate result.

Peak Bins:

Before defining peaks, ensure that the dF/dT sign is correct for the data set to give positive peaks.

Threshold:

To define a bin, click the “New Bin” button, then click and hold on the graph to define the center of the bin. To add another bin, repeat the process. Use the “Remove” button to delete bins.

To set the threshold (y axis), click the icon, then click and hold on the graph and drag the threshold line to the desired level.

Threshold:

To set a temperature threshold (x axis), click the icon, then click and hold on the graph and drag the threshold line to the right. This eliminates the threshold line for the lower temperatures.

Reports

This opens the “Report Browser” where a report can be chosen to preview. A report can be generated based upon the currently selected channel, or a multichannel genotyping report can be generated.

Results

This displays the “Melt Curve Results” window which shows sample peaks.

Genotypes

Click “Genotypes…” and select the genotypes, as shown below.

7-42 Rotor-Gene Q User Manual 02/2012

Analysis User Interface

This window allows genotypes to be assigned to the incidence of peaks in bins. The default genotype configuration is shown in the screenshot, with heterozygous samples having 2 peaks, homozygous samples a peak in the first bin, and wild type samples a peak in the second bin. An abbreviation can be typed into the field next to the name of each genotype. This is used when printing multichannel genotyping reports, so that all results from multiple channels can be easily read.

For multiplex analysis, genotypes must be set up in each channel. If, for example, a dual-channel quenched FRET analysis is run, where a wild type and heterozygous genotype are expected in each channel, the bin parameters must be set up for each channel. The results will then be given in a multiplex report.

Melt analysis templates

Melt analysis templates allow the user to export normalization, threshold, genotype, and bin settings into a single *.met file. This file can be imported and reapplied in

other experiments. See Section 8.1 for more details.

7.6.6 Comparative quantitation

Comparative quantitation compares the relative expression of samples to a control sample in a run when a standard curve is not available. This is frequently used in microarray

analysis. Warton and coworkers (2004)* provide an example

of this technique.

1. To perform the analysis, select “Other” and then

“Comparative quantitation” in the “Analysis” window.

Double-click on the channel to analyze.

Analysis User Interface

2. Choose a control sample using the drop-down menu on the right-hand side of the screen below the toggler.

3. The results are automatically calculated and displayed in the “Comparative Quantitation Results” window below the graph.

The first columns of the “Comparative Quantitation Results” window show the sample number and name. The "Takeoff" column gives the takeoff point of the sample. The second derivative of the amplification plot produces peaks corresponding to the maximum rate of fluorescence increase in the reaction. The takeoff point is defined as the cycle at which the second derivative is at 20% of the maximum level, and indicates the end of the noise and the transition to the exponential phase.

This graph shows a second derivative of an amplification plot, showing the relative positions of the second derivative peak and the takeoff point.

7-44

The “Amplification” column provides the efficiency of the sample. A 100% efficient reaction would result in an amplification value of 2 for every sample, which means that the amplicon has doubled in every cycle. In the raw data, the signal should be doubling in the exponential phase. For example, if the signal was 50 fluorescence units at cycle 12 and then 51 fluorescence units at cycle 13, it should increase

Rotor-Gene Q User Manual 02/2012

Analysis User Interface to 53 fluorescence units at cycle 14. All of the amplification values for each sample are averaged to produce the amplification value that is shown on the right of the screen under the toggler. The greater the variation between the estimated amplification values of each sample, the larger the confidence interval will be (indicated by the value after the ± sign). The confidence interval, for a large sample number

(N), gives a 68.3% probability that the true amplification of the samples lies within this range (1 standard deviation). By doubling the ± interval, a 95.4% confidence interval for a large N is achieved.

Calibrator Replicate

As in the delta delta C

T

method, a calibrator sample is required, and measurements are relative to this calibrator sample. Replicates of the calibrator can be analyzed since, if multiple sample positions have the same name, the average of the takeoff points of these samples will be used. To use this feature correctly, ensure that replicates have identical names.

The average amplification is used to calculate expression.

For example, a sample with a low amplification value will take longer to reach a certain absolute copy number than a sample with a higher amplification value. The “Rep. Conc.” column of the “Comparative Quantitation Results” window provides the relative concentration. The relative concentration of each sample compared with the calibrator sample is calculated based on the takeoff point and the reaction efficiency. This is expressed in scientific notation.

Note: The value displayed in “Average Amplification” to the right of the ± represents the standard deviation of the average amplification, after removal of outlier amplification

Rotor-Gene Q User Manual 02/2012 7-45

Analysis User Interface

7.6.7 values. If this value is large, then there may be a large error in the overall calculated concentration values.

Relative concentrations are calculated by the software as follows:

1. The takeoff point of each sample is calculated by looking at the second derivative peaks.

2. The average increase in raw data 4 cycles after the takeoff is calculated. This is the amplification value for the sample.

3. Outlier amplifications are removed to account for noise in background fluorescence.

4. The remaining amplifications are averaged. This is the average amplification.

5. The average takeoff point is calculated for each calibrator replicate.

6. The relative concentration for a sample is calculated as

Amplification^(Calibrator takeoff – Sample takeoff).

7. The result is displayed in scientific notation in the “Rep.

Conc.” column of the “Comparative Quantitation

Results” window.

Allelic discrimination

Allelic discrimination uses real-time kinetic data from 2 or more channels to genotype samples. To perform this analysis, select “Other” and then “Allelic Discrimination” in the “Analysis” window. When performing allelic discrimination, it is not sufficient to double-click on one channel to analyze because this analysis is performed using multiple channels simultaneously. To perform this analysis, either hold down CTRL and click to highlight each channel you wish to analyze, or drag the mouse pointer over these channels. Once the desired channels have been highlighted, click “Show”. The list will update to show all the channels on one line, with a checkmark beside them. This indicates that they will all be used in one analysis. To remove one or more of these channels, right click on the analysis and select

7.6.9 EndPoint analysis

EndPoint analysis allows discrimination between amplified and unamplified samples at the end of a run. Results are qualitative (positive/negative), not quantitative.

Rotor-Gene Q User Manual 02/2012 7-51

Analysis User Interface

EndPoint analysis is shown in the screenshot below.

7-52

EndPoint analysis is similar to allelic discrimination, in that the results are qualitative, and that names can be assigned to certain permutations of reactions over different channels.

However in EndPoint analysis, only a single reading is available, in contrast to allelic discrimination, which uses a cycle-by-cycle reading for each sample. This means that the user must identify positive and negative controls to facilitate the analysis. For the raw data, signal levels are normalized relative to the known positive and negative controls for each channel. The user then selects a percentage signal level as the threshold.

Terms used in EndPoint analysis

Some terms used in EndPoint analysis are explained below.

Positive control: This is a sample which is known to amplify.

Negative control: This is a sample which is known not to amplify. This represents the typical background signal.

Rotor-Gene Q User Manual 02/2012

Threshold:

The threshold is a signal level above which a sample is said to be positive (amplified).

This setting must be adjusted by the user for each run.

To perform EndPoint analysis, perform a profile with a hold at 50°C for several minutes, then a cycling step with 1 step

(50°C for 10 seconds), acquiring on the required channel.

Set the number of repeats to 5, as shown above. These times are a guide only, and may vary for your particular application. The more repeats in the profile, the more information available to perform the analysis. The analysis will automatically average all the readings to achieve a single value for each sample. There is no specific number of repeats required. Unless a very high level of accuracy is required, 5 repeats are usually sufficient.

Click “OK”. The “Edit Samples” window appears, allowing positive and negative controls to be defined. To define a sample as a positive or negative control, click on the sample type cell, then select the relevant control type from the dropdown menu.

This screen functions in the same way as the “Edit Samples”

Normalization

Normalization of EndPoint analysis data scales all signal levels to within the range of 0–100%. At least one positive and one negative control must be selected, or more if analyzing multiple channels and the standards are not multiplexed. More than one positive and one negative control should be run if there is a risk that a positive control may not amplify.

1. For each channel, all the positive controls are analyzed, and the one with the highest fluorescence is set to be

100%. This means that if duplicate controls are run, a positive control can fail without affecting the run.

2. All the negative controls are analyzed, and the one with the lowest fluorescence level is set to be 0%.

Sample 1 was the positive control with the highest fluorescence, so it was set to 100%. The other positive control was slightly lower. Sample 4, the lowest negative control was set to 0%. It is now clear that sample 5 has probably amplified, whereas sample 6 has probably not amplified.

Note: Depending on the positive and negative controls selected, it is possible to achieve expression levels of greater than 100% or less than 0%. A result of greater than 100% can be interpreted to mean that the sample is more highly

Rotor-Gene Q User Manual 02/2012 7-57

Analysis User Interface expressed than the positive controls. A result of less than 0% can be interpreted to mean that it is less likely that the sample amplified than that the negative controls amplified.

Since this analysis is qualitative, such results are not a concern.

If the negative controls result in higher fluorescence than the positive controls, the samples have been incorrectly set up and the following message appears.

7-58

Normalization in multiple channels

It is possible to analyze signal data over multiple channels, but the sample setup is more complex. EndPoint analysis assumes that multiplexing is performed and so each tube can only have a single tube position. It is not currently possible to analyze a setup in which a sample position is a positive control for one channel and a negative control for another.

Although only one sample definition per tube position is given in the “Edit Samples” window, normalization occurs independently for each channel.

If a tube position is a positive control for at least one channel, it should be specified as a positive control in the

“Type” column of the “Edit Samples” window. Otherwise, its type should be “Sample”. This also applies for negative controls.

For example, if a sample is a positive control in the green channel, but not in the yellow channel, the sample should

Rotor-Gene Q User Manual 02/2012

Analysis User Interface still be defined as a positive control. Since the highest positive control in each channel is used, if there is least one positive control in the yellow channel that amplifies, the definition of the sample as a control for the green channel is ignored.

Threshold

The threshold is used to determine the percentage expression required for a reaction in each channel. Once the positive and negative controls have been defined, all channels will be normalized to the same 0–100% scale. For this reason, only one threshold is needed, even when analyzing multiple channels.

Click and drag the threshold line to an area between 0 and

100. The threshold should not be too close to samples on either side of the line because this indicates that the run was not conclusive. If the difference between a sample being defined as amplified or not amplified is just a few percent, this means that if the reaction were repeated, the sample could appear on the other side of the threshold.

Genotypes

This option opens the “Genotyping” window, which is used to define which genotype is detected in each channel.

This window allows genotypes to be assigned to channels. In the example above, a sample is heterozygous if readings in

7.6.10 Concentration analysis

Concentration analysis allows the Rotor-Gene Q to be used to measure DNA concentrations or to obtain fluorometer readings.

The screenshot below shows this analysis.

7-60 Rotor-Gene Q User Manual 02/2012

Analysis User Interface

Preparing a run

To perform concentration analysis, first prepare fluorescent standards and samples, ideally in triplicate.

Preparation of standards

A standard curve is used to determine the concentration of

DNA from each sample measured.

The DNA used for the standard curve should be a similar type of DNA as in the samples being measured. The concentration of at least one DNA sample should be determined using ultraviolet spectrophotometry, and this sample should be used as the standard. A minimum of 3 standards (with replicates) should be used. Importantly, DNA standards used in fluorescence detection are only linear within the range of 1–100 ng/µl. Within this range, if the concentration of DNA is halved, so is the fluorescent reading.

The confidence intervals for any concentration outside this range are very broad due to nonlinearity of the chemistry.

Type of DNA measured

Differences have been observed in the measurement of various forms of DNA (e.g., genomic DNA compared to plasmid DNA). Therefore, only similar DNA types should be measured together, and the use of plasmid DNA as a standard should be avoided when measuring genomic DNA.

Run setup

To set up the run, select “Nucleic Acid Concentration

Measurement” from the Quick Start wizard.

Note: Ensure that a positive control, such as a high concentration standard, is run in tube position 1. Without a positive control, the software will be unable to optimize gain settings for maximum sensitivity. You will be prompted for this before each run.

Analysis

Concentration analysis operates by relating the fluorescence level to a concentration value. Two analysis models are available. The optimal analysis to chose depends on the chemistry and application.

“Linear Regression” analyzes data by assuming a linear relationship and estimating unknown values on the basis of a generated linear model. It determines measurement error by examining the deviation of the readings from a linear model.

Rotor-Gene Q User Manual 02/2012

7.6.11

Analysis User Interface

If concentration readings are linear, this is the most suitable analysis because it provides statistical analysis of variation

(ANOVA) to the user.

“Spline Curve Fit” assumes only that concentration values increase with fluorescence. While this approach makes estimates of nonlinear data more accurate, it cannot provide

ANOVA, as it does not assume a linear model.

High Resolution Melt analysis

High resolution melt (HRM) analysis characterizes samples based on sequence length, GC content, and complementarity. HRM analysis is used in genotyping applications, such as analysis of gene mutations or single nucleotide polymorphisms (SNPs), and in epigenetics applications for analysis of DNA methylation status. HRM analysis provides accurate results and savings on probe and label costs compared to other methods.

To perform the analysis, select “Other” and then “High

Resolution Melt Analysis” in the “Analysis” window.

Double-click on the channel to analyze. The melt curves from the raw channel are normalized by averaging all starting and ending fluorescence values and then forcing the end points of each sample to be the same as the average.

Green, yellow, orange, and red channels are standard configurations for 4-channel multiplex detection.

Tube Layout

If using a 72-Well Rotor, samples can be arranged to closely match the labeling on a 9 x 8 block. By default, the tube layout tab allows samples to be labeled sequentially (i.e., 1,

2, 3…). This means that samples are labeled consecutively in the order in which they are placed in the Rotor-Gene Q.

Alternatively, samples can be labeled 1A, 1B, 1C, etc. This option can be useful if samples were set up with a multichannel pipet.

Security

The security tab displays information about the run signature.

The run signature is an irreversible key that is regenerated every time the file is changed. If any section of the *.rex file is modified outside the software, the signature and the file will no longer match. Checking the signature allows confirmation that the raw data was not modified outside the application, that the profile has not been tampered with, and that the temperature graph is valid. The signature also protects against corruption such as file-system errors.

Note: If *.rex files are e-mailed, the encryption process can invalidate the signature. To avoid this, zip the file before emailing.

Sample Page Suitability

To access the “Sample Page Suitability” window, click on

“More Options” in the “Edit Samples” window, and then click on “Define Suitabilities”. The “Sample Page Suitability” window allows users to match sample pages to channels. For example, the sample page for the gene of interest may apply to the green channel, and the sample page for the housekeeper gene may apply to the yellow channel. In this example, setting up sample page suitability reduces the number of analysis options available to just include those relevant for the particular assay.

Rotor-Gene Q User Manual 02/2012

7.9

Analysis User Interface

Security menu

The Rotor-Gene Q software includes features that enable it to operate securely. When correctly configured, the

Rotor-Gene Q software can ensure the following:

Access to the Rotor-Gene Q or the analysis software is restricted to user groups

Modifications to run files are logged

Unauthorized modifications are detected (signatures)

Templates used to perform runs are logged

Sample names are protected

Integration with Windows security

To provide a strong level of accountability, Rotor-Gene Q software does not manage security internally. Accounts, groups, and passwords are all managed using the Windows built-in security model. Integration allows the same password that provides access to network files and programs to control

Rotor-Gene Q software access, leading to less administration. In larger organizations, for example, network administrators can easily remove access to ex-users due to the centralized security model.

For this reason, setting up the Rotor-Gene Q software securely primarily involves configuration of the Windows security roles according to best practices.

Prerequisites

To use security, you must be running Windows XP

Professional. The security features cannot be used with

Windows XP Home, as it does not have the fine-grained access model used by the software. The software must be installed with the “Force Authentication through Windows NT

Logon” option.

Note: The Security menu will not appear if you are logged into a Linux Samba domain. You must have either a local logon or a Windows server to use the security features.

Rotor-Gene Q User Manual 02/2012 7-83

Analysis User Interface

7.9.1 Configuration

This section describes how to set up the system to run

Rotor-Gene Q software securely.

To use the security features, the software must be installed with the “Force Authentication through Windows NT Logon” option. This queries the Windows domain for your access level and credentials and is essential for providing the accountability and security features.

Disable simple log in

A more secure way to log in to Windows is to disable the simple login using the “Welcome screen”. To change the login screen to the classic logon prompt, follow these instructions.

1. From the “Start” button, select “Settings”, then “Control

Panel”, followed by “User accounts”.

2. Select “Change the way users log on or off” from the dialog box.

3. In the next window, disable the option “Use the Welcome screen”, and then click “Apply Options”.

7-84 Rotor-Gene Q User Manual 02/2012

Running as administrator

Many users run their computers as an administrator, with no password. While this is convenient, it makes it impossible to determine who is using the computer. This eliminates accountability and prevents many Rotor-Gene Q software security measures from activating. When running as an administrator, all the software features are enabled.

Therefore running as an administrator ensures that users who do not need security features can access all the software features.

Creating a new user account

Create user accounts for each user of the software. For each user, repeat the steps below until all accounts have been created.

1. To create a new user, select “Start/Settings/Control

Panel”.

3. The domain is either the computer you are logging into or the name of your local network. Consult your network administrator if unsure which domain to enter in this field.

Note: After logging in, all of the user files will be available for that user. Each user can save files in their own area. This ensures a high level of security.

Note: Each user should log out after their run has been completed to prevent other users from performing a run in their name.

Audit trails

Every time a file is saved by a user, their details are recorded in “Run Settings” under the “Messages” tab as Security Audit

Trail Summary and Security Audit Trail Detail.

Rotor-Gene Q User Manual 02/2012 7-95

Analysis User Interface

This can be used to monitor who has modified the contents of a file. The Security Audit Trail Detail contains more detail, such as the unique identifier of the user. This identifier is important to avoid a user creating an account with the same name on another computer and thereby impersonating another user. In this case, the user names will be the same, but the account IDs will be different.

7-96 Rotor-Gene Q User Manual 02/2012

Analysis User Interface

The identifier for the account CORIT001/RGQ User 2, S-1-5-

21-1177238915-195, is shown in the details.

7.9.4 Run Signatures

The audit trail is stored in the Rotor-Gene Q run file. To avoid any unwanted modification of these files, they should be kept in a safe location accessible only by designated

Windows accounts. However, if files are stored in a shared area, Run Signatures provide extra security. The screenshot shows the “Security” tab in Run Settings for a file with a Run

Signature.

Rotor-Gene Q User Manual 02/2012 7-97

Analysis User Interface

7-98

The Run Signature is a long word that is generated each time the file is saved and linked to the contents of the file. For example, the signature for this file is

517587770f3e2172ef9cc9bd0c36c081. If the file is opened in Notepad and an edit is made (e.g., the run date is changed to 3 days earlier), the following message appears when the file is reopened.

Rotor-Gene Q User Manual 02/2012

Analysis User Interface

7.9.5

Note: If files are e-mailed, the encryption process can invalidate the signature. To avoid this, zip the file before e-mailing.

Sample locking

It is important to ensure that sample names are not accidentally or intentionally changed once a user has started a run. For this reason, the Rotor-Gene Q software provides sample locking. Sample names can be locked by any user but can only be unlocked by an administrator. For users who run their computers in administrator mode, this option is of limited value. To use this option, the computer must be configured securely as described in the previous sections.

Note: If you wish to lock samples, do not run the software as an administrator. Create an account with RG Operator and

RG Analyst groups, and keep the administrator password secret. Users will then require authorization from the administrator to unlock files.

Rotor-Gene Q User Manual 02/2012 7-99

Analysis User Interface

Samples can be locked before starting a run when using the

Advanced wizard, by clicking “Finish and Lock Samples”.

The following warning will appear. Click “Yes” to confirm.

Once the samples are locked, it will not be possible to edit samples in the “Edit Samples” window.

7-100 Rotor-Gene Q User Manual 02/2012

Analysis User Interface

Samples can also be locked and unlocked in the “Edit

Samples” window. However, only an administrator can unlock samples once they have been locked.

7.9.6

Any unauthorized change to the file will invalidate the Run

Signature.

Locked templates

It is currently not possible for the user to create read-only template files using the Rotor-Gene Q software. However, if desired, it can be specified as a requirement that all runs are performed using a specific template file. In order to ensure read-only access to this template, it should be stored on a network drive where users cannot modify data. Users can still run and modify their own profiles, while the template on a network drive such as this is protected. In order to track which template has been used, the Rotor-Gene Q software stores the name of the template file that was run. This

Some analyses require the user to define thresholds, normalization settings, and genotype settings. Often these settings are reused frequently in multiple experiments.

Analysis templates enable the user to save and reuse these settings. This reduces the effort of reentering settings and reduces the risk of error.

Quantitation, Melt, Allelic discrimination, Scatter graph analysis, and EndPoint analysis support analysis templates.

These analyses allow the user to export a template that is unique to the analysis (e.g., Quantitation analysis allows export and import of *.qut files that contain quantitation settings).

After an analysis template has been imported or exported, the filename of the template is displayed for future reference.

Maintenance Procedures

Maintenance Procedures

Maintaining the working performance of the Rotor-Gene Q is easy. Optical performance is maintained by ensuring that the lenses, located at both the emission and detection source, are clean. This is achieved by gently wiping a cotton tip

applicator, moistened with ethanol*, over the lenses.

Note: Clean the lenses at least once a month, depending on usage. Wipe the rotor chamber at the same time.

Keep the work bench area clean and free from dust and sheets of paper. The air inlet of the Rotor-Gene Q is at the bottom and loose material such as paper or dust may compromise performance.

To avoid dust build up, keep the lid of the Rotor-Gene Q closed when the instrument is not in use.

If the rotor chamber becomes contaminated, it can be cleaned by wiping the surfaces with a lint-free cloth dampened (but not dripping) with a 0.1% (v/v) bleach solution.* Wipe the chamber with a lint-free cloth dampened with PCR-grade water to remove traces of bleach.

*

When working with chemicals, always wear a suitable lab coat, disposable gloves, and protective goggles. For more information, consult the appropriate material safety data sheets (MSDSs), available from the product supplier.

Optical Temperature Verification

Optical Temperature Verification

Optical Temperature Verification (OTV) is a method that verifies the in-tube temperature in a Rotor-Gene Q.

Validation of in-tube temperature can be an important procedure in certified laboratories. OTV is performed using a

Rotor-Disc OTV Kit (see Appendix E).

In the following, only a short introduction to the OTV principle is given. Performance of the OTV procedure is explained in the Rotor-Gene Q software. For a more detailed description of the OTV procedure, including a troubleshooting guide, please refer to the Rotor-Disc OTV

Handbook.

OTV principle

OTV uses the optical properties of 3 thermochromatic liquid

crystals (TLC)* as absolute temperature references. When

heated, TLCs change from opaque to transparent at very precise temperatures (50°C, 75 °C, and 90 °C). TLCs do not themselves fluoresce. Therefore, it is necessary to cover the excitation source with a fluorescent insert so that the TLC transition points can be detected by the Rotor-Gene Q optical system. TLCs that are below their transition temperature are opaque and reflect light. Some of the reflected light scatters towards the detector, increasing fluorescence. When the in-tube temperature reaches the TLC transition point, the TLC becomes transparent, and light passes through the sample rather than being reflected toward the detector, resulting in a decrease in fluorescence.

The change in fluorescence is used to determine the precise transition temperature of each TLC. The transition temperature is compared with the temperature reported by the factory calibration file for the OTV Rotor-Disc to verify

High Resolution Melt Analysis

High Resolution Melt Analysis

High resolution melt (HRM) analysis is an innovative technique that is based on analysis of DNA melting. HRM characterizes DNA samples according to their dissociation behavior as they transition from double-stranded DNA

(dsDNA) to single-stranded DNA (ssDNA) with increasing temperature (see Figure below). A HRM instrument collects fluorescent signals with extremely high optical and thermal precision, creating many application possibilities.

A typical HRM plot. The melt curve plots the transition from the high fluorescence of the initial premelt phase, through the decrease in fluorescence of the melt phase, to the basal level of fluorescence at the postmelt phase. Fluorescence decreases as DNA intercalating dye is released from dsDNA as it melts into single strands. The midpoint of the melt phase, at which the rate of change in fluorescence is greatest, defines the melting temperature (T m

) of the DNA under analysis.

Before performing HRM analysis, the target sequence must be amplified to a high copy number. This is usually performed by PCR in the presence of a dsDNA intercalating fluorescent dye. The dye does not interact with ssDNA but actively intercalates with dsDNA and fluoresces brightly when intercalated. Change in fluorescence can be used to

Rotor-Gene Q User Manual 02/2012 11-1

High Resolution Melt Analysis measure the increase in DNA concentration during PCR and then to directly measure thermally-induced DNA melting by

HRM. During HRM, fluorescence is initially high because the sample starts as dsDNA. Fluorescence decreases as the temperature is raised and DNA dissociates into single strands. The observed melting behavior is characteristic of a particular DNA sample.

Using HRM, the Rotor-Gene Q can characterize samples based on sequence length, GC content, and DNA sequence complementarity. HRM can be used in genotyping applications, such as analysis of insertions/deletions or single nucleotide polymorphisms (SNPs), or to screen for unknown genetic mutations. It can also be used in epigenetics applications for detection and analysis of DNA methylation status. It can also be used to quantitatively detect a small proportion of variant DNA in a background of wild-type sequence at sensitivities approaching 5%. This can be used, for example, to study somatically acquired mutations or changes in the methylation state of CpG islands.

HRM on the Rotor-Gene Q facilitates multiple applications, including:

Identification of candidate predisposition genes

Association studies (comparing cases and controls, genotype to phenotype)

Determination of allele prevalence within a population or subgroup

SNP screening and validation

Screening for loss of heterozygosity

DNA fingerprinting

Characterization of haplotype blocks

DNA methylation analysis

DNA mapping

Species identification

Mutation discovery

Determining the ratio of somatic acquired mutations

Guidelines for successful HRM analysis

The success of HRM analysis depends largely on the particular sequence under investigation. Certain sequence motifs, such as hairpin loops or other secondary structures, localized regions of unusually high or low GC content, or repeat sequences can all affect the outcome. In addition, use of standardized kits and optimized protocols from QIAGEN can overcome many of the potential challenges listed. Some simple guidelines to help ensure success are detailed below.

Analyze small DNA fragments

Analyze fragments no greater than about 250 bp. Larger products can be analyzed successfully but usually provide lower resolution. This is because, for example, a single base variation has a greater effect on the melting behavior of a

100 bp amplicon than on a 500 bp amplicon.

Ensure that PCR contains only specific product

Samples contaminated with post-PCR artifacts such as primer dimers or nonspecific products can make HRM results difficult to interpret. Kits from QIAGEN for HRM analysis ensure maximum specificity with no need for optimization.

Use sufficient preamplification template

Analysis of real-time PCR data can be very useful when troubleshooting HRM analyses. Amplification plots should have a C

T

(threshold cycle) of less than or equal to 30 cycles.

Products that amplify later than this (due to low starting template amount or template degradation) typically produce variable HRM results due to PCR artifacts.

Normalize template concentration

The amount of template added to the reaction should be consistent. Normalize the starting concentrations so that all amplification plots are within 3 C

T

values of each other. This ensures input concentrations are within a 10-fold range.

Rotor-Gene Q User Manual 02/2012 11-7

High Resolution Melt Analysis

Check for aberrant amplification plots

Prior to running HRM, examine amplification plot data carefully for abnormal amplification plot shape. Plots with a log–linear phase that is not steep, is jagged, or that reaches a low signal plateau compared to other reactions, can indicate poor amplification or a fluorescence signal that is too low (e.g., this could occur if primer concentration was too low). Poor reactions can be caused by reaction inhibitors or incorrect reaction setup. HRM data from such samples can be inconclusive or of low resolution. To avoid unreliable results, we recommend QIAGEN kits for sample preparation and HRM analysis.

Keep postamplification sample concentrations similar

The concentration of a DNA fragment affects its melting temperature (T m

). For this reason, sample DNA concentrations must be kept as similar as possible. When analyzing PCR products, ensure that every reaction has amplified to the plateau phase. At plateau, all reactions will have amplified to a similar extent irrespective of their starting amount. Note however, that poor reactions may not reach plateau with the same amplified quantity due, for example, to inconsistent assay setup (e.g., the primer concentration was too low).

Ensure sample-to-sample uniformity

All samples must be of equal volume and should contain the same concentration of dye. DNA melting behavior is affected by salts in the reaction mix, so it is important that the concentration of buffer, Mg, and other salts are as uniform as possible in all samples. Similarly, use only identical reaction tubes from the same manufacturer to avoid variations due to plastic thickness and autofluorescence properties.

11.7

High Resolution Melt Analysis

Allow sufficient data collection for premelt and postmelt phases

Capture HRM data points over approximately a 10°C range, centered around the observed T m

(see figure on page 11-1).

This provides sufficient baseline data points for effective curve normalization and will result in more reproducible replicates and easier data interpretation.

Sample preparation

Sample degradation should be avoided during purification and storage. Avoid excessive amounts of inhibitors, such as from ethanol carryover. To improve HRM results, we recommended keeping the amount of template used consistent between samples. Spectrophotometric analysis for determining DNA concentration and purity is recommended.

We recommend QIAGEN kits for sample preparation.

Note: At 260 nm one absorbance unit is equal to 50 µg/ml

DNA. Pure DNA will provide a 260 nm to 280 nm ratio of

8. Set HRM run conditions. Modify the conditions to suit the amplicon. For the first set of experiments allow for a wide melt domain. Use the theoretical T m

as a guide to a suitable range. Once you have determined where the product will melt, reduce the melt domain to no greater than 10°C. Ensure that the start of the melt occurs 5°C prior to the first melt transition. The default ramp is set to

0.1°C with a hold of 2 seconds at each step. The minimum ramp transition is 0.05°C with a second hold at each step. Data is automatically acquired to the HRM channel. Automatic Gain Optimisation is performed by default. The software will search for the optimal gain setting so that the highest fluorescence value reported is no greater than 70 units on a scale of 100. Note that this can be increased to a maximum of 100.

11.8 Real-time PCR data analysis

Analysis of the real-time PCR data prior to HRM data analysis is advantageous. Real-time PCR data can highlight poorly performing assays. Identifying these outliers and filtering them out of subsequent HRM analysis will greatly improve the overall effectiveness of HRM analysis, since analyzing poor-quality PCR product will result in poor HRM results. We recommend analyzing quantitative real-time PCR data as follows.

1. Analyze the real-time data using the “Quantitation” option from the “Analysis” window. If any C

T

values are

30 or higher, the corresponding reactions are considered to have amplified too late. These samples must be analyzed with suspicion or removed from the analysis as an outlier. Late amplification is usually due to too little starting template amount and/or high levels of sample degradation.

Rotor-Gene Q User Manual 02/2012 11-17

High Resolution Melt Analysis

2. Assess the end-point fluorescence level. If end point fluorescence in any of the amplification plots is low compared with the majority of plots in the data set, omit those samples from the analysis even if their C

T

value is less than 30. Low end-point fluorescence can indicate incorrect dye amount, incorrect levels of reaction components (such as primers), or the action of inhibitors.

3. Use the “Comparative Quantitation” option from the

“Analysis” window to obtain the reaction efficiency of each sample. If the efficiency is not similar to other reactions in the experiment, or is less than approximately

1.4, omit the reaction as an outlier.

11-18

Comparative quantitation results. The reaction efficiency is shown in the “Amplification” column as a score out of 2 (2 = 100% efficiency).

Note: If you suspect the presence of primer–dimers or nonspecific products, assess reactions by drawing a derivative plot using the “Melt” option from the

“Analysis” window. Ensure that there is a single peak, indicative of a single product. If possible, run a gel to check that there is a single amplification product. If there is more than one product, the reaction should be repeated or reoptimized.

Rotor-Gene Q User Manual 02/2012

11.9

High Resolution Melt Analysis

HRM data analysis

HRM analysis enables both visual- and auto-calling of genotypes. Results can be viewed as either a normalized melt plot or a difference plot. Normalized curves provide the basic representation of the different genotypes based on curve shifting (for homozygotes) and curve shape change (for heterozygotes).

Difference plots are an aid to visual interpretation. They plot the difference in fluorescence of a sample to a selected control at each temperature transition. Difference plots provide an alternative view of the differences between melt curve transitions.

Note: First derivative melt curve analysis (as used by the standard “Melt” option in the “Analysis” window) is considered inappropriate for HRM analysis. This is because any derivation of the data adds artificial noise and makes data interpretation more difficult.

The following steps describe the analysis of HRM results using Rotor-Gene Q software.

1. Select the “HRM” option from the “Analysis” window.

Rotor-Gene Q User Manual 02/2012 11-19

High Resolution Melt Analysis

2. Windows appear showing the raw data, the normalized graph, and the results. The raw data window allows adjustment of the regions of normalization.

Normalization allows all the curves to be compared with the same starting and ending fluorescent signal level to aid interpretation and analysis. Two cursors per region are provided, defaulted to the ends of the curve. The data points within the regions are used to normalize fluorescence (the y axis only) for the start (Region 1) and end (Region 2) of the melt plot. Data outside the set regions are ignored. Adjust the regions to encompass representative baseline data for the premelt and postmelt phases. Widening the regions (by clicking and dragging) allows the software to adjust for the slope of the baseline. To ensure curves normalize effectively, avoid widening the normalization regions into the melt phase.

11-20

Note: We recommend cursors are only moved if you wish to avoid areas of the melt curve. Movement of the cursors toward the melt phase transitions can affect subtraction plots and confidence percentages.

3. The “Normalised Graph” window displays the normalized melt curves. Samples can also be viewed as a difference plot against one of the controls.

Acquisition

Bins

Channel

Gain

Glossary

Description

Acquisition is the collection of fluorescent data. Each acquisition (set of fluorescent data) from a channel is displayed in the software as unanalyzed data in a “Raw channel” window. This data can be analyzed using the options in the “Analysis” menu.

In a melt analysis, bins are set to define a region where a melt peak is expected to occur. Genotypes can be defined based on the presence of peaks in certain bins or combinations of bins.

A channel consists of a light emitting diode (LED) with an excitation filter paired with an emission filter. The LED and excitation filter excite samples at a given wavelength.

Fluorescence emitted by samples is passed through the emission filter, before being detected by a photomultiplier.

The Rotor-Gene Q uses a photomultiplier to collect fluorescence photons and convert them to electronic signals.

The gain is a setting that determines the sensitivity of the photomultiplier. If the gain is set too high, the signal is oversaturated. If the gain is set too low, it is not possible to differentiate signal from background noise.

Gain

Optimisation

Gain Optimisation is a process that dynamically adjusts the gain setting, allowing an appropriate setting to be selected which results in optimal signal detection.

Loading Block Loading Blocks are aluminum blocks available in different formats which are used to hold tubes or Rotor-Discs during reaction setup. Rotor-Disc Loading Blocks are also used with the Rotor-Disc Heat Sealer to heat seal Rotor-Discs.

Locking Ring Locking Rings are metal rings that fit onto the rotor to prevent tubes and caps from coming loose during operation of the Rotor-Gene Q. Loose caps and tubes could cause damage to the instrument.

The log concentrations and C

values of the standards are used to construct a model in the form: y = Mx + B

Confidence intervals for calculated concentrations

We use the following confidence interval 100(1-

α)% for an estimate of a new observation x0 from the standard curve.

This is the confidence interval for the concentration of a single unknown.

Suppose now we have k further observations at x = x0 and we denote their average by . Then, and arguments similar to above give

This formula determines how confidence intervals for concentrations of replicate unknowns are determined.

Rotor-Gene Q User Manual 02/2012 D-1

Appendix D

For estimation of standards, a tighter confidence interval can be obtained:

The implication of this formula is that adding replicates to an standard individual concentration reduces the width of the interval for all estimates, as n is increased. Adding a large number of replicates to an unknown reduces its uncertainty to that of a single standard. The extra replicates reduce the uncertainty due to the unknown not forming part of the linear model.

Confidence intervals for C
