REAGENT STORAGE AND USE
1. Refer to kit component packaging label for proper storage temperatures.
2. If salts have precipitated out of solution during shipping or storage, resolubilize completely prior to use by vortexing at room
temperature (18 to 30°C).
3. Probe mixes and R-Phycoerythrin Conjugated Streptavidin are light sensitive. Keep away from light. Do not freeze these
reagents.
4. Do not use R-Phycoerythrin Conjugated Streptavidin that has been frozen during shipment or storage.
5. Do not use components past their expiration dates.
GENOMIC DNA PREPARATION AND USE
1. DNA can be prepared using any preferred method. The assay has been tested on genomic DNA from whole blood.
CAUTION: All biological and blood samples should be treated as potentially infectious. Use Universal Precautions when
handling.
2. DNA extracted from blood preserved in heparin cannot be used in this assay.
3. The presence of alcohol, detergents or salts may adversely affect DNA amplification.
4. Absorbance measurements of the DNA sample should yield a 260nm to 280nm ratio ranging from 1.65 to 2.0.
5. The isolated DNA should be resuspended and stored in 10mM TRIS, pH 8.0 to 9.0, or in nuclease free water. If a chelating
agent such as EDTA is present, the final concentration of the chelating agent should not exceed 0.5mM.
6. Final DNA concentration should be 10 to 200 ng/µL.
7. DNA can be used immediately after isolation or stored at –20ºC for up to 1 year. Repeated freeze/thawing should be
avoided since this can result in DNA degradation.
WARNING AND PRECAUTIONS

2.
3.
4.
For Research Use Only – Not for in vitro diagnostic use.
Separate pipettes should be designated for Pre-PCR manipulations as well as for Post-PCR manipulations.
All biological and blood samples should be treated as potentially infectious. Use Universal Precautions when handling.
Dilution Solution, Probe mixes, Taq Polymerase and R-Phycoerythrin Conjugated Streptavidin contain hazardous
compounds. Avoid contact with skin and eyes and dispose of accordingly. See Material Safety Data Sheets for additional
information (www.gen-probe.com).

PROCEDURE
A. Genomic DNA Purification:
1. See Genomic DNA Preparation and Use for important information.
2. Purify DNA using method of choice.
3. Final concentration of genomic DNA should be 10 to 200 ng/ul.
4. Adjust DNA concentrations, if necessary, using nuclease free water. Keep all samples at similar concentrations.
B. Amplification:
1. Bring Master Mix kit component to room temperature.
2. Prepare Master Mix reaction solution using the following table. Prepare immediately prior to use. Do not store. Total
volume per reaction is 25µL. It is recommended that one water blank be run with each test.

3. Aliquot DNA (~100ng optimal; 40 to 200ng acceptable) into PCR tubes.
4. Aliquot Master Mix reaction solution into tubes. Discard any remaining Master Mix reaction solution.
5. Place samples in the thermal cycler and run amplification program. The program shown below has yielded optimal
results in internal testing. Conditions may need to be altered in order to optimize thermal profiles for individual
thermal cyclers used.

Warm Probe Mix at 55º to 60ºC for 5 to 10 minutes.
Sonicate and vortex Probe Mix briefly to thoroughly resuspend the beads.
Aliquot 15µL of Probe Mix into each well of a Costar plate (vortex Probe Mix after every 8 samples).
Aliquot 5µL of PCR product into each well.
Seal plate with polyethylene tape or film.
Place in thermal cycler and run hybridization program. Use a rubber mat or metal plate to prevent evaporation.

8. At the 56C HOLD step, dilute each sample with 170L of the Dilution Solution/PE-Streptavidin mixture.
NOTE: Do not remove the tray from the thermal cycler until all samples have been diluted.
9. Remove the sample tray from the thermal cycler and immediately place in the Luminex instrument for analysis.
NOTE: For best results, acquisition should begin within 5 minutes after hybridization program ends.
D. Analysis Using Luminex Instrument (refer to Luminex IS User’s Manual for instrument operation, including daily
startup, calibration, maintenance, and shutdown procedures):
1. Turn on the Luminex Instrument between 30 minutes and 4 hours before assaying the samples.
2. Import the lot specific IDT template provided on the “RBC Lot Information Update CD” using the Luminex IS User’s
Manual. Please note that the template versions are lot number specific and correspond to the kit lot numbers.
3. Prior to analyzing the samples on the Luminex Instrument, set up a Batch Run by which the samples will be
analyzed. For example, if analyzing an RBC run, add a Batch Run for RBC.
a. Select Create a New Batch from the File menu.
b. Follow the stepwise instructions that appear on the screen for creating batches.
c. When naming the batch, do not include commas in the name; information located after a comma will be
lost in data export.
d. For further instructions on creating batches and multibatches, refer to the Luminex IS User’s Manual.
4. Click the Eject icon to eject the plate holder. Place the 96 well thermal cycler plate containing the samples in the
XYP heater block present on the plate holder.
5. Click the Retract icon. The samples are now ready to be analyzed. An instrument priming step should be
performed before starting the run.
6. After the samples have been run through the instrument, a sanitization step with 70% Isopropanol or 20% household
bleach should be performed followed by two wash steps. The instrument can be turned off at this point if it is not
going to be used for the remainder of the day.
7. After a batch is complete, the data are exported as a Comma Separated Values (csv) file. These files are named
‘OUTPUT.CSV’ and saved in a folder with the Batch Name entered into the Luminex IS. These data are then
available for analysis using the MATCH IT!-RBC software.
E. Analysis Using Lifecodes MATCH IT!-RBC Software:
1. Import the lot specific EDS file provided on the “RBC Lot Information Update CD" using the Lot Data Set Import
tab.
2. Import the csv file obtained from Luminex analysis using the Batch Data Import tab.
3. Analyze the batch using the User’s Manual for MATCH IT!-RBC Software.
4. See User’s Manual for MATCH IT!-RBC Software User’s Manual for a description of possible run results.
a. Indeterminate results are noted by an "ID" label in the software report.
b. Indeterminate (ID) results can occur due to low amplification, probe value too close to the cut off, or an
unexpected rare result. In these cases, the sample should be repeated or typed using another red cell typing
technology.

TROUBLESHOOTING
PROBLEM
Low Bead Count
POSSIBLE CAUSE
Probe Mix not well suspended
Instrument not
functioning properly
Out of Calibration
Sample flow path blocked
“Failed” sample
Sample failed to amplify
or amplified poorly
Low DNA
SOLUTION
Prewarm, sonicate, and vortex probe mix and repeat
assay.
Calibrate instrument (refer to Luminex IS User’s
Manual).
Remove and sonicate needle. Perform backflush.
Call Lifecodes Technical Support if problem persists
(888-329-0255).
Check DNA concentration and purity (see Genomic
DNA Preparation and Use).
Salts in Master Mix are out of
solution
Heat Master Mix at 37ºC for 5 minutes, vortex gently,
and spin down briefly (2 to 5 secs).
Poor Taq Polymerase
Use only Recombinant Taq. Lifecodes Cat. No.
167075 is recommended.
Run thermal profile on thermal cycler to verify
parameters are within specified parameters. Adjust if
necessary.
Ensure Dilution Solution is stored at room temperature
(18 to 30 ºC).
Warm Dilution Solution at 45ºC for 5 minutes before
use and vortex.
Replace R-Phycoerythrin Conjugated Streptavidin.
Amplification conditions not within specific parameters
Low Median Fluorescent Intensity (MFI) value
Evaporation during hybridization
Ensure the plate is sealed tightly.
If not using an entire plate, leave one row empty on
each side of samples to be assayed to assist in
obtaining a tight plate seal.
SPECIFIC PERFOMANCE CHARACTERISTICS
Specific performance characteristics have not been determined.
