Safety information
Safety information
Note: For general safety information, see this section and Appendix G, “Safety” on
page 237. When a hazard symbol and hazard type appear by a chemical name or
instrument hazard, see the “Safety” Appendix for the complete alert on the chemical or
instrument.
Safety alert words
Four safety alert words appear in Life Technologies user documentation at points in
the document where you need to be aware of relevant hazards. Each alert
word—IMPORTANT, CAUTION, WARNING, DANGER—implies a particular level
of observation or action, as defined below:
IMPORTANT! – Indicates information that is necessary for proper instrument
operation, accurate chemistry kit use, or safe use of a chemical.
CAUTION! – Indicates a potentially hazardous situation that, if not avoided,
may result in minor or moderate injury. It may also be used to alert against
unsafe practices.
WARNING! – Indicates a potentially hazardous situation that, if not avoided,
could result in death or serious injury.
DANGER! – Indicates an imminently hazardous situation that, if not avoided,
will result in death or serious injury. This signal word is to be limited to the most
extreme situations.
Except for IMPORTANTs, each safety alert word in a Life Technologies document
appears with an open triangle figure that contains a hazard symbol. These hazard
symbols are identical to the hazard symbols that are affixed to Life Technologies instruments
(see “Safety symbols” on page 238).
Safety data sheets
(SDSs)
The SDSs for any chemicals supplied by Life Technologies or Ambion are available to
you free 24 hours a day. For instructions on obtaining SDSs, see “SDSs” on page 246.
IMPORTANT! For the SDSs of chemicals not distributed by Life Technologies or
Ambion contact the chemical manufacturer.

About the QuantStudio™ 12K Flex System
About the QuantStudio™ 12K Flex System
The Applied Biosystems QuantStudio™ 12K Flex Real-Time PCR System uses
fluorescent-based polymerase chain reaction (PCR) reagents to provide:
• Quantitative research detection of target nucleic acid sequences (targets) using
real-time analysis.
• Qualitative research detection of targets using post-PCR (endpoint) analysis.
• Qualitative analysis of the PCR product (achieved by melt curve analysis that
occurs post-PCR).
About data
collection
The Applied Biosystems QuantStudio™ 12K Flex Real-Time PCR System collects raw
fluorescence data at different points during a PCR, depending on the type of run that
the QuantStudio™ 12K Flex Instrument performs:
Run type
Real-time
Standard curve‡
Relative standard curve‡
Data collection point
The QuantStudio™ 12K Flex Instrument collects
data following each extension step of the PCR.
Comparative CT (ΔΔCT)

Genotyping
Presence/absence‡
The QuantStudio™ 12K Flex Instrument collects
data:
• Before the PCR.
For presence/absence experiments, data
collection before the PCR is optional, but
recommended.
• (Optional) During the PCR.
The QuantStudio™ 12K Flex Instrument can
collect data during the run (real-time); collecting
real-time data during the run can be helpful for
troubleshooting endpoint results.
• After the PCR.
‡ Not available for OpenArray® experiments.

Regardless of the run type, a data collection point or read consists of three phases:
1. Excitation – The QuantStudio™ 12K Flex Instrument illuminates all wells of the
reaction plate within the instrument, exciting the fluorophores in each reaction.
2. Emission – The QuantStudio™ 12K Flex Instrument optics collect the residual
fluorescence emitted from the wells of the reaction plate. The resulting image
collected by the device consists only of light that corresponds to the range of
emission wavelengths.
3. Collection – The QuantStudio™ 12K Flex Instrument assembles a digital
representation of the residual fluorescence collected over a fixed time interval.
The QuantStudio™ 12K Flex Software stores the raw fluorescent image for
analysis.
After a run, the QuantStudio™ 12K Flex Software uses calibration data to determine
the location and intensity of the fluorescent signals in each read, the dye associated
with each fluorescent signal, and the significance of the signal.

Barcode reader
The Applied Biosystems QuantStudio™ 12K Flex Real-Time PCR System can include
two barcode readers for data entry and plate recognition:
• A hand-held barcode reader for scanning plates manually.
• A fixed-position barcode reader for automatically scanning plates as they are
loaded into the instrument (available only with the Twister® Robot).
Both barcode readers use 670 nm Class II lasers to scan plates, and both readers are
capable of reading Code 128 (alphanumeric), which supports 128 ASCII character
barcodes. The barcode readers are optional and available depending on the system
configuration.
About the hand-held barcode reader
WARNING! LASER HAZARD. Exposure to direct or reflected laser light can
burn the retina and leave permanent blind spots. Never look into the laser beam.
Remove jewelry and anything else that can reflect the beam into your eyes.
Protect others from exposure to the beam.
The optional hand-held barcode reader functions as an extension of the keyboard. You
can use the reader to scan barcodes into the QuantStudio™ 12K Flex Software.
To scan a barcode using the hand-held barcode reader:
1. In the QuantStudio™ 12K Flex Software, select the field where you want to enter
the barcode.
2. Hold the barcode reader 20–30 cm away from a plate and aim at the center of the
barcode, then press the trigger. Slowly move the scanning beam across the
barcode until the reader emits a high-pitched tone.
When the reader scans a barcode, it automatically:
• Transmits the alphanumeric equivalent of the barcode to the QuantStudio™ 12K
Flex Software. The software enters the barcode text wherever the cursor is active.
• Transmits a carriage-return character (the equivalent of pressing the Enter key).
For more information on the hand-held barcode reader, see the barcode reader user
documentation shipped with the QuantStudio™ 12K Flex System.

QuantStudio™ 12K Flex System hardware
Electrical
protective devices
1
We recommend several devices to protect the QuantStudio™ 12K Flex System in
environments with large voltage and power fluctuations.
Power line regulator
We recommend the use of a 1.5-kVA power line regulator in areas where the supplied
power fluctuates in excess of ± 10% of the normal voltage. Power fluctuations can
adversely affect the function of the QuantStudio™ 12K Flex System.
Note: A power line regulator monitors the input current and adjusts the power
supplied to the QuantStudio™ 12K Flex System or computer. It does not protect
against a power surge or failure.
Uninterruptible power supply (UPS)
We recommend the use of a 1.5-kVA uninterruptible power supply (UPS), especially in
areas prone to power failure. Power failures and other events that abruptly terminate
the function of the QuantStudio™ 12K Flex System can corrupt data and possibly
damage the computer or the instrument.
IMPORTANT! UPSs provide power for a limited time. They are meant to delay the
effects of a power outage, not to serve as replacement power sources. In the event of a
power loss, power off the instrument and the computer, unless you expect to regain
power within the battery life of the UPS.
Surge protector
We recommend the use of a 10-kVA surge protector (line conditioner) in areas with
frequent electrical storms or near devices that are electrically noisy, such as
refrigerators, air conditioners, or centrifuges. Short-duration, high-voltage power
fluctuations can abruptly terminate the function of, and thereby damage the
components of, the computer and the QuantStudio™ 12K Flex Instrument.
Note: A dedicated line and ground between the QuantStudio™ 12K Flex System/
computer and the building’s main electrical service can also prevent problems caused
by power fluctuations.

• Restrict Ethernet communication
• Interfere with QuantStudio™ 12K Flex Software operation (see below)
To confirm that third-party software does not interfere with the QuantStudio™ 12K
Flex Software:
1. Install the software to the computer that contains the QuantStudio™ 12K Flex
Software.
2. Perform several dry-run test experiments using plates that do not contain
reagents.
Note: The goal of the test experiments is to run plates under conditions that
match normal instrument operation. Therefore, the characteristics of the test
experiments (plate layout and run method) must closely resemble your actual
experiments.
3. Confirm that the QuantStudio™ 12K Flex System performs each test experiment
without producing errors.
If the QuantStudio™ 12K Flex System performs the tests successfully, proceed
with your experiments. If the QuantStudio™ 12K Flex System encounters errors
during the test runs, the software may not be compatible with the QuantStudio™
12K Flex Software.

QuantStudio™ 12K Flex System consumables
Guidelines for
handling
consumables
1
Observe the following guidelines when using tubes, plates, or array cards:
• Store the calibration plates or array cards in a dark place until you are ready to
use them. The fluorescent dyes in the wells of calibration consumables are
photosensitive. Prolonged exposure to light can diminish the fluorescence of the
dyes.
• Do not allow the bottoms of tubes or plates to become dirty. Fluids and other
contaminants that adhere to the bottoms of the consumables can contaminate the
sample block and cause an abnormally high background signal.
• Confirm that the centrifuge you use is clean. Before centrifugation, wipe down the
bucket using a tissue.
• (Plates only) Vortex all calibration plates to ensure complete mixing, then
centrifuge them to ensure that all reagents are contained in the bottom of the
wells. The calibration plates must be well mixed and centrifuged before use.
• (Plates only) Do not discard the packaging for the calibration plates. Each plate can
be used to calibrate the QuantStudio™ 12K Flex System 3 times for up to 6 months
if it is stored in its packing sleeve.
• (Plates only) Handle the calibration plates with care to prevent contamination. Do
not place the plates on a lab bench, to avoid contaminating them. Always put
calibration plates back into their packaging sleeves.
• (96-well plates only) If you are using cap strips to seal your plates, firmly seal all
wells before running the plate. Partially seated caps can leak during the
experiment, causing evaporation.
• (Tubes only) Firmly seal all individual tubes and tube strips. Partially seated caps
can leak during the experiment, causing evaporation.
• (OpenArray® plates only) Hold OpenArray® plates by the edges of the cases. Do
not touch the through-holes.
• (OpenArray® plates only) Load and seal the TaqMan® OpenArray® plate within
one hour after opening the plate packaging.
• (OpenArray® plates only) If you drop a loaded OpenArray® plate, discard it in the
appropriate waste container.

7. Place the filled carrier clips into the centrifuge buckets.
Make sure that the array card fill reservoirs and bucket
and clip labels face outward when loaded into the
centrifuge.
IMPORTANT! You must run the centrifuge with all four
buckets in place and each of the two carriers filled with
array cards. Place empty array card into unfilled slots.
IMPORTANT! Balance the loads in opposite buckets in the centrifuge.
8. Close the centrifuge cover, then spin the array card(s) for 1 minute at 1200 rpm.

9. When the run is finished, stop the centrifuge, then spin the array card(s) again for
1 minute at 1200 rpm.
IMPORTANT! Do not try to save time by doing one spin for 2 minutes. The two
sets of ramps are important for a good fill into the array card.
10. When the second run is finished, open the centrifuge and check that the fluid
levels in the reservoirs of each array card have decreased by the same amount.
Also, check for the formation of bubbles in all wells and note possible problems.
Correct fill
Incorrect/partial fill
If necessary, centrifuge the array cards for an additional minute to fill any unfilled
wells. Do not exceed three 1-minute runs or centrifuge the array card for longer
than 1 minute at a time.
11. Seal the array card(s):
Staker Seal Use
a. With the carriage (roller assembly) of the Array
Card Staker/Sealer in the Start position, place a
filled array card into the fixture with the foil side
up so that the fill reservoirs are the farthest away
from the carriage.
b. Press down on all four corners of the array card to
ensure that it is fully seated within the fixture.
Alignment pins
c. Use the two alignment pins in the fixture to
position the array card correctly.
d. Seal the array card by running the carriage slowly
over it. Run the carriage over the array card in one
direction only. Do not apply downward force on
the carriage as you move it forward over the card.

e. Remove the sealed array card from the fixture and
trim the fill reservoirs from the array card
assembly using scissors. Trim the foil array card so
that the edge is even with the plastic carrier.
IMPORTANT! Completely remove the fill reservoirs
from the array card so that the edge is free of
residual plastic. The plastic from the fill reservoirs
that extends beyond the edge of the card can
prevent the array card from seating properly on
the sample block and can affect amplification.
Correct trim
Incorrect trim
12. Repeat step 11 to seal the remaining array cards.
IMPORTANT! As you seal the remaining filled array cards, store them in a dark place.
Do not expose the array cards to light until you are ready to use them. The dyes in the
array cards are photosensitive. Prolonged exposure to light can diminish the
fluorescence of the dye.
IMPORTANT! If an array card is sealed improperly, the card may leak and contaminate
the sample block and/or it can cause the associated calibration or RNase P experiment
to fail.

Chapter 2 Calibrating Multi-Well Plate and Array Card Sample Blocks
ROI calibration
2
ROI calibration
A regions of interest (ROI) calibration maps the positions of the wells on the sample
block of the QuantStudio™ 12K Flex Instrument. The QuantStudio™ 12K Flex Software
uses the ROI calibration data to associate increases in fluorescence during a run with
specific wells on the plate. The QuantStudio™ 12K Flex Instrument uses a set of optical
filters to distinguish the fluorescence emissions gathered during runs. You must
generate a calibration image for each filter to account for minor differences in the
optical path.
When to perform
the calibration
Perform the ROI calibration every year, or as often as necessary, depending on
instrument use.
IMPORTANT! After every ROI calibration, you must perform a background calibration,
uniformity calibration, dye calibration, normalization calibration, and RNase P
instrument verification experiment.
About the ROI
calibration data
During the ROI calibration, the QuantStudio™ 12K Flex Software captures images of
the ROI calibration plate at each instrument filter. An ROI calibration passes if the
collected image for each filter shows all wells of the ROI plate or array card. Each well
in the image must be distinct and visible at the same luminosity relative to the other
wells in the image.
You can review the ROI calibration image for each filter set by selecting the desired
filter combination from the Filter Set menu of the ROI tab in the Instrument Manager.
Status
Image
Passing image
Green circles appear around all wells
indicating that the wells calibrated
successfully. Each green circle indicates that
the region of interest for the well position is
sufficiently bright.
Failing image
Red circles appear around some or none of
the wells indicating that the wells did not
calibrate. The absence of a circle indicates
that the region of interest for the well
position is not sufficiently bright.

Background calibration
2
Background calibration
During a background calibration, the QuantStudio™ 12K Flex System:
• Performs reads of a background plate containing PCR buffer for 10 minutes at
60°C.
• Averages the spectra recorded during the run and extracts the resulting spectral
component to a calibration file.
The QuantStudio™ 12K Flex Software then uses the calibration file during subsequent
runs to remove background fluorescence from the run data.
When to perform
the calibration
Perform the background calibration monthly or as often as necessary, depending on
instrument use.
About the
background
calibration data
During the background calibration, the QuantStudio™ 12K Flex Software captures a
series of images of the background plate using each instrument filter. The software
compares the fluorescence from each well to the average for the plate. A background
calibration passes if the collected images for all filters are free of abnormal
fluorescence.
About the data
After the calibration, you can review the calibration data in the Background tab of the
Instrument Manager. The Analysis Data plot (left-side) displays the fluorescence data
in all filters. The Well Table tab (right-side) displays the data collected for the current
calibration. The QC tab displays a summary of quality check performed by the
QuantStudio™ 12K Flex Software on the calibration data.
Background fluorescence
Fluorescence data collected by the QuantStudio™ 12K Flex Instrument includes a
fluorescence signal inherent to the system, referred to as “background fluorescence”.
Background fluorescence is a composite signal found in all spectral data that consists
of fluorescence from several sources, including:
• Background electronic signal
• Contaminants in the sample block
• The plastic consumable (plate or array card)

Dye calibration
2
Dye calibration
During a dye calibration, the Applied Biosystems QuantStudio™ 12K Flex Real-Time
PCR System:
• Collects spectral data from a series of dye standards.
• Stores the spectral information for the dye standards in a dye calibration file.
The QuantStudio™ 12K Flex Software uses the pure spectra data during experiment
runs to characterize and distinguish the individual contribution of each dye in the total
fluorescence collected by the QuantStudio™ 12K Flex Instrument. After each run, the
QuantStudio™ 12K Flex Software receives data in the form of a raw spectra signal for
each reading. It determines the contribution of each fluorescent dye used in the sample
by comparing the raw spectra to the pure spectra calibration data. When you save an
experiment after analysis, the QuantStudio™ 12K Flex Software stores the pure spectra
with the collected fluorescence data for that experiment.
IMPORTANT! Calibrate only those dyes that are present in the chemistries that you
intend to run on your QuantStudio™ 12K Flex System.
When to perform
the dye calibration
Perform a dye calibration every year, or as often as necessary, depending on
instrument use.
IMPORTANT! Calibrate only dyes that are present in the chemistries that you intend to
run on the QuantStudio™ 12K Flex System. For example, if you intend to run a
TaqMan® RNase P plate or array card to verify instrument performance (see page 63),
you must calibrate the FAM™ dye, TAMRA™ dye, and ROX™ dye because all three are
present in the TaqMan® assay chemistry.
IMPORTANT! Perform a background calibration before every series of dye calibrations.
Because the age and use of instrument components can affect spectra readings, we
recommend performing a dye calibration at least every year.
About the dye

System dyes
The Applied Biosystems QuantStudio™ 12K Flex Real-Time PCR System calibrates the
following system dyes: FAM™ dye, NED™ dye, ROX™ dye, SYBR® Green dye,
TAMRA™ dye, and VIC® dye. The following figure shows the emission spectrum for
each dye, and the filters and wavelengths at which each dye is read.

Dye calibration
Custom dyes
The QuantStudio™ 12K Flex System can be used to run assays designed with custom
dyes (not supplied by Life Technologies); however, before using custom dyes with the
QuantStudio™ 12K Flex System, you must create and run a custom calibration plate.
The QuantStudio™ 12K Flex Software uses the custom calibration plate to create a
spectral standard to distinguish the custom dye in the fluorescence data collected
during the run. See “Creating a custom dye plate for calibration” on page 184 for
information on custom dye calibrations.
IMPORTANT! A custom dye must excite between 455 and 672 nm and read between 505
and 723 nm.
About the dye calibration data
The product of a dye calibration is a collection of spectral profiles that represent the
fluorescence signature of each dye standard. Each profile consists of a set of spectra
that correspond to the fluorescence collected from the wells of the spectral
calibration plate. The QuantStudio™ 12K Flex Software plots the resulting data for
each spectral profile in a graph of fluorescence versus filter.
When the QuantStudio™ 12K Flex Software extracts the dye calibration data, it
evaluates the fluorescence signal generated by each well in terms of the collective
spectra for the entire calibration plate. Dye spectra are generally acceptable if they
peak within the same filter as their group but diverge slightly at other wavelengths
(see below).
The QuantStudio™ 12K Flex Software can compensate for some differences in a
spectral profile by replacing the spectra of unacceptable wells with the spectra of other
wells on the reaction plate (auto-repairing). The QuantStudio™ 12K Flex Software
allows only a few replacements, and it may reject the calibration if the spectra between
neighboring wells vary significantly.
Note: Because the wells of a calibration plate contain identical concentrations of a dye,
the resulting signals for the wells should be similar. Variations in spectral position and
peak position are caused by minor differences in the optical properties and excitation
energy between the individual wells.

Acceptable spectra
Unacceptable spectra
Spectra peak at the same wavelength and
do not diverge significantly.

The QuantStudio™ 12K Flex Software performs the same analysis of data from an
instrument verification runs for 96-well plate, Fast 96-well plate, 384-well plate, or
array card blocks.
After the run, the QuantStudio™ 12K Flex Software:
1. Generates a standard curve from the averaged threshold cycle (CT) values of the
replicate groups of standards.
2. Calculates the concentration of the two unknown populations using the standard
curve.
3. Calculates the following to assess the QuantStudio™ 12K Flex System
performance:
[(CopyUnk2) – 3(σCopyUnk2)] > [(CopyUnk1) + 3(σCopyUnk1)]
where:
• CopyUnk1 = Average copy number of unknown population A
• σCopyUnk1 = Standard deviation of unknown population A
• CopyUnk2 = Average copy number of unknown population B
• σCopyUnk2 = Standard deviation of unknown population B
Note: Unknown population A refers to the 5,000-copy population in columns
7–15 of the TaqMan® RNase P Plate or the 800-copy population in rows C and D
of the loaded array card. Unknown population B refers to the 10,000-copy
population in the wells of the TaqMan® RNase P Plate or the 1,600-copy
population in rows E and F of the loaded array card.

7. When the run is complete and the QuantStudio™ 12K Flex Software displays the
Analysis screen, verify the status of the run.
Analysis status
Action
Passed
The QuantStudio™ 12K Flex System passed the RNase P run. Go to
step 12 on page 70.
Failed
The QuantStudio™ 12K Flex System failed the RNase P run. Go to
step 8 to review the data for outliers.
If the run fails, the QuantStudio™ 12K Flex Software may have
included outliers that caused the initial analysis to fail.
Experimental error may cause some wells to be amplified
insufficiently or not at all. These wells typically produce CT values
that differ significantly from the average for the associated replicate
wells. If included in the calculations, these outlying data (outliers)
can result in erroneous measurements.
8. In the Amplification Plot, select Ct vs. Well from the Plot Type menu, then verify
the uniformity of each replicate population (controls, standards, and unknowns)
on the reaction plate by comparing the groupings of CT values:
a. In the plate layout, select the wells containing Unknown Population A:
• 96-well plate – Select rows A–C (5,000-copy population).
• 384-well plate – Select columns 7–15 (5,000-copy population).
• Array card – Select rows C and D (800-copy population).
b. In the plot, verify that the CT values of the replicate population are
equivalent.
Note: The numbers on the X-axis of the plot correspond to the wells of the
reaction plate. Beginning with well A1, the wells are numbered from left-toright, and top-to-bottom.
c. If an outlier is present in the selected population, select the corresponding
well of the plate layout, then click Omit to remove the well from the analysis.
If the total number of outliers for the replicate population exceeds the limit in
the table below, repeat the experiment using another RNase P plate or array

Identifying
contamination
Signals that exceed the limit of normal background fluorescence may indicate
fluorescent contaminants on the calibration plate or the sample block. Common
contaminants include ink residue from permanent pens, powder from disposable
gloves, and dust.
To determine the source and location of the contamination:
1. While viewing the background calibration data in the Analysis screen, select the
QC tab and review the list of wells that failed the quality check.
2. Rotate the background plate 180° , then perform the background calibration
again.
3. Determine the location of the contaminated wells again.
If the position(s) of the contaminated well(s) in step 1 and step 2 are:
• Identical – The sample block is contaminated. Decontaminate the sample
block.
• Reversed – The background plate or array card is contaminated. Discard the
plate or array card, then perform the background calibration using a new
background plate or array card.
4. If the calibration fails after you replace the background plate and decontaminate
the sample block:
a. Cover a plate or array card with a piece of black paper.
b. Perform the background run as explained in this chapter, substituting the
plate or array card covered with paper for the background plate or array
card.
c. After the run is complete and while viewing the calibration data, select all
wells in the Plate Layout tab, then view the Spectral plot for the peak(s). If
the peak associated with the contamination is:
• Visible – The optics of your QuantStudio™ 12K Flex System may be
contaminated. Contact Life Technologies for further support.
• Absent – The sample block is contaminated. Decontaminate the sample
block again and repeat the calibration.

Dye calibration
Dye calibration
IMPORTANT! Perform the following procedure only if you are calibrating a
QuantStudio™ 12K Flex System with an OpenArray® plate sample block.
During a dye calibration, the Applied Biosystems® QuantStudio™ 12K Flex Real-Time
PCR System:
• Collects spectral data from the FAM™ dye standard.
• Stores the spectral information for the dye standard in a dye calibration file.
The QuantStudio™ 12K Flex Software uses the pure spectra data during experiment
runs to characterize and distinguish the individual contribution of dyes in the total
fluorescence collected by the QuantStudio™ 12K Flex Instrument. After each run, the
QuantStudio™ 12K Flex Software receives data in the form of a raw spectra signal for
each reading. It determines the contribution of each fluorescent dye used in the sample
by comparing the raw spectra to the pure spectra calibration data. When you save an
experiment after analysis, the QuantStudio™ 12K Flex Software stores the pure spectra
with the collected fluorescence data for that experiment.
IMPORTANT! Calibrate only those dyes that are present in the chemistries that you
intend to run on your QuantStudio™ 12K Flex System.
Required materials
• QuantStudio™ 12K Flex System Installation/Calibration Kit:
– OpenArray® FAM™ Dye Solution
– QuantStudio™ 12K Flex System OpenArray® Calibration Cases (4)
– QuantStudio™ 12K Flex System OpenArray® Plugs (4)
– QuantStudio™ 12K Flex System OpenArray® Calibration Syringe and Tip
• OpenArray® Plate Press 2.0
• Pipettes
• Powder-free gloves
• Safety glasses
When to perform
the dye calibrations
Perform a dye calibration at least once per year or more often, depending on use.
IMPORTANT! You must perform a background calibration before every dye calibration.
Because the age and use of instrument components can affect spectra readings, we
recommend performing a dye calibration at least every year.

Chapter 3 Calibrating OpenArray® Plate Sample Blocks
Dye calibration
About the dye
calibration
3
The dye calibration is a two-part procedure in which the QuantStudio™ 12K Flex
Instrument performs two readings of the OpenArray® Calibration Cases:
• A preread of the empty OpenArray® Calibration Cases
• A postread of the OpenArray® Calibration Cases filled with OpenArray® FAM™
Dye Solution
About the dye calibration data
The product of the dye calibration is a spectral profile that represents the fluorescence
signature of the FAM™ dye standard. The profile consists of a set of spectra that
correspond to the fluorescence collected from the OpenArray™ calibration cases. The
QuantStudio™ 12K Flex Software plots the resulting data for the spectral profile in a
graph of fluorescence versus filter.
When the QuantStudio™ 12K Flex Software extracts the dye calibration data, it
evaluates the fluorescence signal generated by each OpenArray™ calibration case in
terms of the collective spectra for the entire tool. Dye spectra are generally acceptable if
they peak within the same filter as their group but diverge slightly at other
wavelengths.
The QuantStudio™ 12K Flex Software can compensate for some differences in a
spectral profile by replacing the spectra of unacceptable wells with the spectra of other
regions of the OpenArray™ Calibration Case (auto-repairing). The QuantStudio™ 12K
Flex Software allows only a few replacements, and it may reject the calibration if the
spectra between neighboring wells vary significantly.
Guidelines for
handling the
OpenArray®
Calibration Cases
• Wear gloves that are one size smaller than the size you typically wear, to help
prevent excess glove material from contacting the OpenArray® Calibration Cases
while loading.
• Hold OpenArray® Calibration Cases by the edges.
• If you drop a loaded OpenArray® calibration case, discard it in the appropriate
waste container.
Perform the empty

Troubleshooting
Identifying
contamination
Signals that exceed the limit of normal background fluorescence may indicate
fluorescent contaminants on the calibration plate or the sample block. Common
contaminants include ink residue from permanent pens, powder from disposable
gloves, and dust.
To determine the source and location of the contamination:
1. While viewing the background calibration data in the Analysis screen, select the
QC tab and review the list of through-holes that failed the quality check.
2. Rotate the background plate 180° , then perform the background calibration
again.
3. Determine the location of the contaminated through-holes again.
If the position(s) of the contaminated through-hole(s) in step 1 and step 2 are:
• Identical – The sample block is contaminated. Decontaminate the sample
block.
• Reversed – The background plate is contaminated. Discard the plate, then
perform the background calibration using a new background plate.
4. If the calibration fails after you replace the background plate and decontaminate
the sample block:
a. Cover a OpenArray® plate with a piece of black paper.
b. Perform the background calibration as explained in this chapter, substituting
the OpenArray® plate covered with paper for the background plate.
c. After the run is complete and while viewing the calibration data, select all
through-holes in the Plate Layout tab, then view the Spectral plot for the
peak(s). If the peak associated with the contamination is:
• Visible – The optics of your QuantStudio™ 12K Flex System may be
contaminated. Contact Life Technologies for further support.
• Absent – The sample block is contaminated. Decontaminate the sample
block again and repeat the calibration.
Viewing the ROX™
image files
You can export quality control (QC) images from RNase P experiments. The QC
images include: calibration images, a barcode image, and images taken during the run.
You can view the images to check that calibration was correct or to validate the data.
To export QC images from an RNase P experiment:
1. In the Instrument Manager, click Export while viewing the results of the RNase P
run.
2. In the Export screen, select a location for the file. Click Browse if you do not want
to save the image files to the default export folder.
Note: To set up the Export File Location, go to ToolsPreferences, select the
Export tab, then select Use Last File Location or Use Default Folder. If you do not
specify a directory to receive the image files, the software exports the files to the

Regular data maintenance
Regular data maintenance
Maintaining the
computer hard
drives
Defragment and clean up the hard drive:
• At least once every month.
• When a message is displayed by the Windows® operating system instructing you
to defragment.
For more information on maintaining the hard drives, see the Windows® Operating
System Help, then search the Help to find information on the Disk Cleanup and Disk
Defragment utilities.
IMPORTANT! Do not run the disk management utilities and QuantStudio™ 12K Flex
Software at the same time.
Archiving and
backing up
experiment files
Archive experiment files regularly
To conserve space on the computer hard drive, older EDS files can be archived using a
data compression utility. Several commercial compression utilities are available to
store experiment files in the ZIP or ARC archive format.
Back up experiment files
We strongly recommend that you back up your experiments. Backing up data:
• Protects against potential loss of data caused by failure of the computer or its hard
drive(s).
• Conserves space on the hard drive and optimizes performance.
Develop a data management strategy
We recommend developing a strategy for managing the files produced by the
QuantStudio™ 12K Flex Software.
Note: Real-time runs generate significantly more data than genotyping or presence/
absence experiments. During 24 hrs of real-time operation, the QuantStudio™ 12K Flex
System can generate more than 10 MB of data.
Check disk space
If you perform real-time experiments on your QuantStudio™ 12K Flex System, check
the amount of available space on your hard drive weekly. When the hard drive is
within 20% of maximum capacity, transfer the older data to another storage device.
Backing up the
instrument
settings
You can use the QuantStudio™ 12K Flex Instrument touchscreen to back up the
instrument settings (instrument name, icon, standby time-out, and cover idle
temperature). In the event that the QuantStudio™ 12K Flex Instrument settings are
reset, you can restore the settings from the backup.
See “Backing up the QuantStudio™ 12K Flex Instrument settings” on page 164 for
more information.

communication. When the QuantStudio™ 12K Flex System is connected to a network,
computers on the network that run the QuantStudio™ 12K Flex Software can:
• Send and download experiments to and from the QuantStudio™ 12K Flex System.
• Run experiments on the QuantStudio™ 12K Flex System.
• Remote monitor the QuantStudio™ 12K Flex System as it performs runs.
The Ethernet port of the QuantStudio™ 12K Flex Instrument supports:
• Static IP network service with subnet mask, primary and secondary data network
service (DNS), and default gateway settings, or dynamic host configuration
protocol (DHCP) network service
• mDNS/DNS for local domains
Note: Because mDNS is limited to direct network connections, a QuantStudio™
12K Flex System set for mDNS may not be visible to other nodes that are
separated by a router, hub, or another network device.
• IPv4 link-local (IPV4LL) in the RFC (also known as Automatic Private IP
Addressing [APIPA] or Internet Protocol Automatic Configuration [IPAC])
Note: When the QuantStudio™ 12K Flex System is set for DHCP, APIPA is
automatically enabled, and the QuantStudio™ 12K Flex System provides an IP

Networking
guidelines and best
practices
• Consult a network administrator.
– We recommend that you consult a network administrator before connecting
the QuantStudio™ 12K Flex System to your laboratory network.
– To enable the full functionality of the QuantStudio™ 12K Flex Software, the
computer requires a network connection.
• Limit remote monitoring to 10 computers.
Avoid using more than 10 computers to simultaneously monitor the
QuantStudio™ 12K Flex Instrument remotely. Although the QuantStudio™ 12K
Flex System supports remote monitoring from multiple computers, each
connection taxes the instrument microprocessor. Too many connections can
overburden the QuantStudio™ 12K Flex System and result in instrument errors.
Note: The effects of an overburdened QuantStudio™ 12K Flex System are evident
in the Temperature Plot during a run. Symptoms can include extended hold times
or brief, unexpected plateaus in the instrument Temperature Plot.
• Observe the restrictions to mDNS and Autodiscovery.
The QuantStudio™ 12K Flex System supports mDNS but only when the
QuantStudio™ 12K Flex Instrument and computer share a direct network
connection and are within the same subnet. Consequently, network computers
that are separated from the QuantStudio™ 12K Flex System by a router, hub, or
another network device may not be able to access the QuantStudio™ 12K Flex
Instrument by its host name.
• Confirm the uniqueness of the instrument name.
The QuantStudio™ 12K Flex Instrument does support name resolution but the
instrument name must be unique within the subnet. The QuantStudio™ 12K Flex
Software can automatically discover QuantStudio™ 12K Flex Instruments on the
link-local network that are configured for Autodiscovery (see “Defining the
network settings” on page 170).
Note: The QuantStudio™ 12K Flex System does not test the uniqueness of the
instrument name when it is set.
• Name QuantStudio™ 12K Flex Instruments using lower-case letters.
When you define the QuantStudio™ 12K Flex Instrument settings (see “Defining
the instrument settings” on page 168), enter the instrument name using lowercase letters only.
Network setup workflow
1. Collect the required network information.
2. Connect the QuantStudio™ 12K Flex Instrument to the network.
3. Connect the computer to the network.
4. Monitor the QuantStudio™ 12K Flex Instrument (to test the network connection).

Security, Audit, and Electronic Signature
Administrators overview
Administrators overview
IMPORTANT! The Security, Audit, and Electronic Signature (SAE) module is installed
only with Applied Biosystems® QuantStudio™ 12K Flex Real-Time PCR Systems that
were purchased with the SAE module.
IMPORTANT! Enabling the Security, Audit, and Electronic Signature module alone
does not make the QuantStudio™ 12K Flex System compliant with any particular
standard. You must modify the module settings according to your requirements to
ensure compliance.
The Security, Audit, and Electronic Signature (SAE) module is an optional component
of the QuantStudio™ 12K Flex Software that can allow you to configure the
QuantStudio™ 12K Flex System to meet specific requirements. The module provides
the following functionality:
• Security – Controls user access to the software. A default Administrator user
account is provided, and additional user accounts and permissions can be userdefined.
Note: The default password for the Administrator user account is Administrator;
however, the password can be changed during installation.
Note: You can enable or disable system security globally.
• Auditing – Tracks changes made to library items, actions performed by users, and
changes to the Security, Audit, and Electronic Signature settings. The software
automatically audits some actions silently. You can select other items for auditing
and specify the audit mode. The Auditing function provides reports for audited
library items, Security, Audit, and Electronic Signature changes, and actions.
Note: You can enable or disable auditing globally and by record type. It is
disabled globally by default.
• Electronic signature (e-sig) – Determines if users are required to provide a user
name and password when performing certain functions. You can configure e-sig
so that a user can print a report or start a run only if the associated data are
signed. You can also configure each e-sig event to require multiple signatures and
to require users with specific permissions to sign.
Note: Electronic signature can be enabled or disabled globally. It is disabled
globally by default.
Example
applications
You can configure the SAE module in a variety of ways. For example, you can:
• Require users to log in, and leave audit disabled.
• Allow only certain users to create or modify protocols.
• Allow only certain users to approve reviewed samples.
• Require experiments to be signed before users can run or print them.

Security, Audit, and Electronic Signature
Users overview
Users overview
The Security, Audit, and Electronic Signature (SAE) module is an optional component
of the QuantStudio™ 12K Flex Software. The module provides the following
functionality:
• System security – Controls user access to the software.
• Auditing – Tracks changes made to library items, actions performed by users, and
changes to the Security, Audit, and Electronic Signature settings.
• Electronic signature – Requires users to provide a user name and password when
performing certain functions.
Depending on the way that your administrator configures these features, you may see
the following dialog boxes and prompts when you use the software.
Security
Logging in
If security is enabled on your system, you must provide a user name and password to
access the software.
Your access to functions in the software is based on the permissions associated with
your user account. Functions for which you do not have permissions are grayed.
Note: If the QuantStudio™ 12K Flex Software is configured for password expiration,
you are periodically prompted to change your password.
Note: If the QuantStudio™ 12K Flex Software is configured to monitor failed log in
attempts, you will be locked out of the software if you incorrectly enter your user name
or password for a specified number of times.
Permissions
If your user account does not have permission to perform any function in the software,
menu commands are grayed.
Changing your
password when it
expires
When your password is about to expire, a message is displayed when you log in.
Account
suspension
If the QuantStudio™ 12K Flex Software is configured to suspend a user account for
failed logins, and you enter an incorrect user name and password for more than the
allowed number of times, your user account is suspended, and the Log In dialog box
indicates that your account is inactive.
To change your password, select ToolsChange Password. Enter your current
password, then enter the new password two times, then click OK.
There are two ways to activate a suspended account:
• You can wait until the suspension period ends.
• An administrator can change the account status from Suspended to Active.
Note: While a user is suspended, another user can click Reset, then log in and replace
the suspended user.

select a reason from the list or enter a reason for change.
Electronic signature
If your system is configured for electronic signature, you may be required to have the
experiment signed by other users before you can print a report or start a run. If an item
is set to require multiple signatures, all approvers must sign the associated data before
the action can be completed.
If electronic signature is enabled for experiments, any of the following may apply:
• The ToolsSecuritySign Data menu option is enabled.
• You are prompted to sign as described in “How the software prompts electronic
signature” on page 152.

SampleNames\SampleFileNames.txt" -c "alloptionsused"
-f "Plate Barcode_Custom Name Field" -b "C:\barcodes.txt”
-v -l "C:\Experiment"
For this example, the command-line application:
• Imports assay definitions from the AIF_820629.txt assay information file.
• Imports sample names from the SampleFileNames.txt sample file.
• Generates an experiment for each barcode in the barcodes barcodes.txt
barcode file, where each new experiment uses the settings found in the
standard_curve.edt template file and the SDS_820629.txt setup file.
Note: The setup file links the information from the AIF_820629.txt and
SampleFileNames.txt to each new experiment file.
• Saves all generated files using the following naming convention:
<barcode>_alloptionsused
• Saves all generated files to:
C:\Experiment\<date/time>
Note: The command-line application automatically creates a time-stamped folder
at the export location for each batch operation. For example, the folder created for
files generated on April 7, 2010 at 12:48:35 would be: 2010-04-07 124835

Import formats and file specifications
The QuantStudio™ 12K Flex Software supports several import file formats that can be
used to automate experiment creation and assay and sample data import. The files can
be used with the command-line application (see page 189) or the QuantStudio™ 12K
Flex Software application programming interface (API) to integrate the QuantStudio™
12K Flex System into a laboratory information management system (LIMS). For a
detailed explanation of the API, or for information on integrating the QuantStudio™
12K Flex System into a laboratory workflow, see the Applied Biosystems QuantStudio™
12K Flex Real-Time PCR System Automation Guide (Part no. 4470693).
Note: The file specifications listed in this appendix are subject to change. For updated
information, review the QuantStudio™ 12K Flex Software Release Notes found at:
C:\Program Files\Applied Biosystems\QuantStudio12KFlex\docs\README.html.

Plate setup file format
Plate setup file format
You can use plate setup files to automatically populate setup information into an open
experiment in the QuantStudio™ 12K Flex Software or into new experiments created
by the command-line application (see page 189). A plate setup file is a tab-delimited
ASCII text file (.txt) that contains data that describes the location experiment data
information. The files can be created manually using a text processor or generated
automatically by third-party applications.
IMPORTANT! To guarantee successful import of the plate setup file into a experiment,
the file must contain all the elements described in the following section and in the
order that they appear.
File structure
The plate setup file consists of a header, which specifies the instrument model for
which the experiment is designed, and a sample setup section.
Section
Plate setup file
header
Description
See…
Plate setup file header
Defines the instrument model for which the
experiment is designed and the dye used as the
passive reference.
page 201
Plate setup file body
Defines the contents of a 96/384-well plate or array
card, including target, SNP assay, sample, and task
assignments.
page 202
The plate setup file begins with a header that consists of two lines. Each line starts with
an asterisk (*) and ends with a carriage return in the following pattern:
* <field name> = <field value>
The header must contain the lines shown in the following table.
Field
Description
Valid values
Instrument
Type
The model of QuantStudio™ 12K Flex
System for which the experiment is
designed.

as a passive reference.
• The name of a dye in the Dye
Library of the QuantStudio™ 12K
Flex Software‡, or
• <blank> if the consumable does
not contain a passive reference.
‡ Custom dyes are allowed if they are in Dye Library.
Note: The QuantStudio™ 12K Flex Software automatically removes any leading and
trailing white space around the field name and field value.

Plate setup file format
Plate setup file
body
The body of a plate setup file contains either target information, which can be
imported into all experiments except genotyping, or SNP assay information. This
information can be imported into genotyping experiments only. The body consists of
three required elements (the header, the column header, and the body) that describe
the contents of a 96/384-well plate or array card. The sample setup column header and
body can appear in any order.
IMPORTANT! Observe the following guidelines when creating a plate setup file:
• Do not insert blank lines between the sample setup header and the column header.
• Do not use illegal characters, including backslash (\), tab, asterisk (*), hard return,
soft return, brackets([ or ]), or comma (,).
Sample setup header
The header contains the label that defines the beginning of the sample setup data.
Example:
[Sample Setup]
Sample setup column header
The column header contains the headings that define the positions of the data columns
in the sample setup body. The headings are separated by tab characters. See “Plate
setup data columns” on page 203 for a list of the data column headers.
Example:
Well Sample Name Sample Color
Biogroup Name Biogroup Color Target Name…
Sample setup body
Contains the sample setup data where each row defines the contents of a single well on
the consumable, including the: well contents (sample, target, or SNP assay added to
the well), task assignments, and comments. If a well contains multiple assays
(multiplex PCR), the data for the additional assays are defined on separate lines by
repeating the well designation. See “Plate setup data columns” on page 203 for a list of
the data column headers.
Note: The sample setup data rows can occur in any order.

Sample file format
The QuantStudio™ 12K Flex Software can import sample files to populate sample
information into an open experiment. A sample file is a tab-delimited ASCII text file
(.txt) that contains sample/well designations, and custom sample properties. The files
can be created manually using a text processor or generated automatically by thirdparty applications.
IMPORTANT! To guarantee successful import, the file must contain all the elements
described in the following section and in the order that they appear.
Note: The command-line application (see page 189) does not import sample files. If
you are using the application to create experiments, use plate setup files to import
sample information into the new experiments (see “Plate setup file format” on
page 201).
File structure
Sample file header row
The sample file begins with an optional header row that contains column headers for
well number (“Well”), sample name (“Sample Name”), and optional custom
properties names. The order of the columns is important and cannot be changed.
Sample file body
A body of rows, containing the sample data, follows the optional header row. Each
body row defines the sample information for a single well on the consumable,
including: well number, sample name, and any applicable custom fields. The body can
contain data for a subset of wells on the consumable, so the rows for empty wells can
be omitted from the file. The sample body rows can occur in any order.

7900 export format
The QuantStudio™ 12K Flex Software can export setup and results data from
experiment files (.eds) to tab-delimited text files (txt) in a legacy export format of the
Applied Biosystems® 7900HT Real-Time PCR System. The 7900 export format features
a standardized data structure and markup to maximize accessibility by downstream
applications. Data exported in the QuantStudio12KFlex export format can be opened
by common spreadsheet applications, such as Microsoft® Excel®, or imported by
laboratory information management system (LIMS) applications that have been
configured to parse the file format.
Note: Due to the very different nature of the QuantStudio™ 12K Flex Instrument some
export types are not available.
Note: Column customization (sorting and omission) is not available. Only multiple
tab-delimited text files are supported.

RDML export format
The QuantStudio™ 12K Flex Software can export data from real-time quantitative PCR
experiments as well-formed Real-time PCR Data Markup Language (RDML), a
structured extensible markup language (XML) standard for quantitative PCR (qPCR)
data. In combination with the Minimal Information (MIQPCR) guidelines, the RDML
element structure describes all aspects of a qPCR experiment, including setup,
analysis, and data interpretation. The exported RDML data is saved as a flat text file
that can be used to transfer qPCR data between the QuantStudio™ 12K Flex Software
and third-party applications.
IMPORTANT! The RDML export format is available only for standard curve, gene
expression, and relative standard curve experiments.
For more
information
228
The RDML standard is maintained by the RDML consortium, an organization that
consists of key developer groups and a member community. For more information on
the RDML format, visit the RDM organization website (www.rdml.org). The website
features free data management tools, including an on-line RDML file generator and
RDML software libraries.

allele
In a diploid organism, one of two DNA sequences found at the same locus (for
example, a particular gene), but located on homologous chromosomes. Two
corresponding alleles may have the identical sequence, or they may differ somewhat,
often at one or more single-base sites (SNPs).

A segment of DNA amplified during PCR.
amplification
Part of the instrument run in which PCR amplifies the target. Fluorescence data
collected during amplification are displayed in an amplification plot, and the data are
used to calculate results.
Note: Only quantitative real-time PCR experiments, not end-point experiments, take
amplification data into account.
amplification
efficiency (EFF%)
Calculation of the efficiency of the PCR amplification in an experiment. EFF% is
calculated using the slope of the regression line in the standard curve. A slope close to
−3.32 indicates optimal, 100% PCR amplification efficiency.
amplification plot
Display of data collected during the cycling stage of PCR amplification. The
amplification plot can be viewed as:
• Baseline-corrected normalized reporter (ΔRn) vs. cycle
• Normalized reporter (Rn) vs. cycle
• Threshold cycle (CT) vs. well
amplification stage
Part of the instrument run in which PCR amplifies the target. The amplification stage,
called a cycling stage in the thermal profile, consists of denaturing, primer annealing,
and extension steps that are repeated. Fluorescence data collected during the extension
stage are displayed in an amplification plot, and the data are used to calculate results.
With TaqMan chemistry, the last two steps of a PCR stage are typically combined.

experiments that contain data from real-time PCR, the magnitude of normalized
fluorescence signal generated by the reporter at each cycle during the PCR
amplification. In the ΔRn vs Cycle amplification plot, ΔRn is calculated at each cycle as:
ΔRn (cycle) = Rn (cycle) −Rn (baseline), where Rn = normalized reporter
In genotyping experiments and presence/absence experiments, the difference in
normalized fluorescence signal generated by the reporter between the pre-PCR read
and the post-PCR read. In the allelic discrimination plot (genotyping experiments) and
the presence/absence plot (presence/absence experiments), ΔRn is calculated as:
ΔRn = Rn (post-PCR read) −Rn (pre-PCR read), where Rn = normalized reporter
See also normalized reporter (Rn).
baseline threshold
algorithm
Expression estimation algorithm (CT) that subtracts a baseline component and sets a

biological replicates
Reactions that contain identical components and volumes, but evaluate separate
samples of the same biological source (for example, samples from three different mice
of the same strain, or separate extractions of the same cell line or tissue sample).
When an experiments uses biological replicate groups in a gene expression study, the
values displayed in the Biological Replicates tab are calculated by combining the
results of the separate biological samples and treating this collection as a single
population (that is, as one sample). For ΔCT computations (normalizing by the
endogenous control) in a singleplex experiment, the software treats separate biological
samples as unpaired data when computing variability estimates of the single biological
replicate. Individual contributions of the separate biological samples to the single
biological replicate results are observed in the Technical Replicates tab.

quencher-minor
groove binder (NFQMGB)
Molecules that are attached to the 3′ end of TaqMan® probes. When the probe is intact,
the nonfluorescent quencher (NFQ) prevents the reporter dye from emitting
fluorescence signal. Because the NFQ does not fluoresce, it produces lower

results in data with noticeably high precision among technical replicates.
plate layout
An illustration of the grid of wells and assigned content in the reaction plate. The
number of rows and columns in the grid depends on the sample block that you use.
In the software, you can use the plate layout as a selection tool to assign well contents,

the post-PCR read are displayed in the presence/absence plot and used to make
detection calls. Also called endpoint read.
pre-PCR read

curve is defined by the number of points in the dilution series, the number of
standard replicates, the starting quantity, and the serial factor.
standard curve
method
Method for determining absolute target quantity in samples. With the standard curve
method, the software measures amplification of the target in samples and in a
standard dilution series. Data from the standard dilution series are used to generate
the standard curve. Using the standard curve, the software interpolates the absolute
quantity of target in the samples.
See also standard and standard curve.
standard dilution
series
In standard curve and relative standard curve experiments, a set of standards
containing a range of known quantities. The standard dilution series is prepared by
serially diluting standards. For example, the standard stock is used to prepare the first
dilution point, the first dilution point is used to prepare the second dilution point, and
so on. In the software, the volumes needed to prepare a standard dilution series are
calculated by the number of dilution points, the number of standard replicates, the
starting quantity, the serial factor, and the standard concentration in the stock. See also
standard curve.
standard quantity
In the PCR reaction, a known quantity. In standard curve experiments, the quantity of
target in the standard. In the software, the units for standard quantity can be for mass,
copy number, viral load, or other units for measuring the quantity of target. Standard
quantity can also refer to dilution factor.
starting quantity
When defining a standard curve in the software, the highest quantity.
step
A component of the thermal profile. For each step in the thermal profile, you can set
the ramp rate (ramp increment for melt curve steps), hold temperature, and hold time
(duration). You can turn data collection on or off for the ramp or the hold parts of the
step. For cycling stages, a step is also defined by the AutoDelta status.
SYBR® Green
reagents
PCR reaction components that consist of two primers designed to amplify the target
and SYBR® Green dye to facilitate detection of the PCR product.

Glossary
system dye
Dye supplied by Life Technologies and precalibrated on the QuantStudio™ 12K Flex
System. Before you use system dyes in your experiments, make sure the system dye
calibration is current in the Instrument Console.
The system dyes are:
• FAM™ dye
• JOE™ dye
• ROX™ dye
• NED™ dye
• SYBR® Green dye
• TAMRA™ dye
• VIC® dye
TaqMan® reagents
PCR reaction components that consist of primers designed to amplify the target and a
TaqMan® probe designed to detect amplification of the target.
target
The nucleic acid sequence to amplify and detect.
target color
In the software, a color assigned to a target to identify the target in the plate layout and
analysis plots.
Target Library
In the software, an editable collection of targets to use in experiments. Targets in the
library contain the target name, reporter, quencher, and target color. The targets in the
library may also contain comments about the target.
task
In the software, the type of reaction performed in the well for the target or SNP assay.
Available tasks:
• Unknown
• Negative Control
• Standard (standard curve and relative standard curve experiments)
• Positive control (genotyping experiments)
• IPC (presence/absence experiments)
• Blocked IPC (presence/absence experiments)
technical replicates
Wells containing identical reaction components, including sample; important for
evaluating precision.
temperature plot
In the software, a display of temperatures for the instrument cover and instrument
block during the instrument run.
template
The type of nucleic acid to add to the PCR reaction.
template file
A user-created file that contains experiment setup information (experiment type,
sample names, target name, and thermal conditions) to be used as a starting point for
new experiment setup. Template files have an .edt extension.
thermal profile
Part of the run method that specifies the temperature, time, ramp, and data collection
points for all steps and stages of the instrument run.

Glossary
• In amplification plots, the level of fluorescence above the baseline and within the
exponential growth region. For the Baseline Threshold algorithm, the threshold
can be determined automatically (see automatic threshold) or can be set manually
(see manual threshold).
threshold
• In presence/absence experiments, the level of fluorescence above which the
software assigns a presence call.
threshold cycle (CT)
The PCR cycle number at which the fluorescence meets the threshold in the
amplification plot.
Tm
See melting temperature (Tm).
touchscreen
Instrument display that you touch to control the instrument.
uniformity
calibration
Type of calibration in which the software measures sample block uniformity. The
calibration generates data that compensate for the physical effects of the
QuantStudio™ 12K Flex System filters on data collected during an experiment.
unknown
In the software, the task for the target or SNP assay in wells that contain the sample
being tested. In quantification experiments, the task for the target in wells that contain
a sample with unknown target quantities. In genotyping experiments, the task for the
SNP assay in wells that contain a sample with an unknown genotype. In presence/
absence experiments, the task for the target in wells that contain a sample in which the
presence of the target is not known. In melt curve experiments, the task for the target
in wells that contain a sample with an unknown melt curve profile.
unknown-IPC wells
In presence/absence experiments, wells that contain a sample and internal positive
control (IPC).
y-intercept
In the standard curve, the value of y where the regression line crosses the y-axis. The yintercept indicates the expected threshold cycle (CT) for a sample with quantity equal
to 1.
