u
Use fresh reagents for each batch of plates, and empty reservoirs between batches.
u
To minimize errors when preparing user-supplied reagents, prepare large batches of 0.1 N NaOH and
95% Formamide/1 mM EDTA using the following guidance.
Preparing Batches of 0.1 N NaOH
Prepare fresh 0.1 N NaOH in large batches. Divide batches into 15 ml or 50 ml sealed tubes.
Store the sealed tubes for 6 months at 2°C to 8°C and use the stored 0.1 N NaOH as needed. Use the 0.1
N NaOH the same day you open the tube, and discard any unused amounts.
Preparing Batches of 95% Formamide/1 mM EDTA
Prepare the 95% formamide/1 mM EDTA mixture in large batches. Divide batches into 15 ml or 50 ml sealed
tubes.
Store the sealed tubes for up to 6 months at -25°C to -15°C and use the stored mixture as needed. Use the
mixture the same day you open the tube, and discard any unused amounts.
Use Fresh RA1 Reagent for Each Step
Use fresh RA1 for each step in the assay where it is required. RA1 that has been stored properly and has not
been dispensed for use in either the XStain or Resuspension step is considered fresh RA1. After RA1 has
been exposed to room temperature air for extended periods of time, it is no longer fresh.
To make best use of RA1, only pour the amount needed for the current step. If you plan to perform additional
assay steps requiring RA1 the same day, leave the remaining thawed reagent in the original, closed bottle at
room temperature until it is needed. Follow the standard RA1 storage procedures described in this guide for
next-day processing and prolonged storage conditions.
Store PB1
For Infinium HD Super workflows do the following.
u
Store PB1 at room temperature.
u
Keep PB1 for up to 3 months.
Tips and Techniques
Unless a safe stopping point is specified, proceed immediately to the next step.
Avoid Cross-Contamination
When adding or transferring samples, change tips between
each sample
.
Measure Volumes Carefully
When measuring volumes of reagent to put in reservoirs, make sure that the measurements are exactly as
specified in the instructions. Do not estimate volumes.
HD Glass Back Plates
u
For optimal performance, use HD glass back plates that are free of chips and cracks along the beveled
edge and the long edges. Chipped or cracked HD glass back plates risk volume leakage and affect
overall performance.
