u
Clean HD glass back plates according to the procedures in the
Infinium Assay Lab Setup and Procedures
Guide (Document # 11322460)
.
u
A 10% bleach soak is required weekly, or every seven uses, to maintain glass performance.
Barcode Numbers
u
Barcode serial numbers used for workflow enforcement and positive sample tracking on MSA plates,
DNA plates, and reagents use a numbering pattern of two alphanumeric characters followed by seven
random numbers.
Sealing the Plate
u
Always seal plates before the vortex and centrifuge steps in the protocol.
u
Orient sealing mats so that the A1 on a cap matches the A1 on the plate.
u
Make sure that all 96 caps are securely seated in the wells to prevent evaporation and spills, which
introduce variability and cross-contamination.
u
Remove sealing mats slowly and carefully to prevent splashing, and then set aside upside-down in a
safe location.
u
When returning a sealing mat to a plate, make sure that the orientation is correct.
Heat Sealer
u
If you are using the ALPS 50 V model heat sealer, set it to 165°C and 2.5 seconds.
Pipetting
u
Make sure that pipettes are properly calibrated, cleaned, and decontaminated.
u
Dispense slowly and carefully to prevent turbulence in the plate wells and flow-through chambers.
u
Use a multichannel pipette whenever possible.
Centrifugation
u
When centrifuging plates or BeadChips, place a balance plate or rack with BeadChips opposite each
plate or rack being centrifuged. Make sure that the weights are as similar as possible.
Washing and Coating BeadChips
Perform the following steps before starting the wash and coat process:
u
Place wash dish covers on wash dishes when not in use.
u
Clean wash dishes with low-pressure air to remove particulates before use.
u
Wash tube racks and wash dishes thoroughly before and after use. Rinse with DI H
2
O. Place them
upside down on wash rack to dry.
u
Prepare an additional clean tube rack that fits the internal dimensions of the vacuum desiccator. Allow
one rack per eight BeadChips.
Handling Hybridization Chambers
u
Keep the chamber lids and bases together. Adopt a labeling convention that pairs each chamber base
with the original lid.
