Enid and other flow cytometry users.
I believe daily measurements should be made using alignment beads in
linear. Preliminary data suggest the larger beads are superior than
smaller beads. However all beads larger than 2.5u can be used under
proper handling conditions. I also believe that sensitivity
measurements should be made daily to insure the machine is clean and not
contaminated. This is my opinion and not that of the ISAC organization.
ISAC is currently in the process of discussing and releasing guidelines
for maintaining, aligning and calibrating flow cytometer. This topic
will be discussed in detail at a workshop on flow cytometry standards in
ISAC 2006 (Quebec City May 20-24) . Naturally, ISAC does not support
or endorse any of the companies products, but only an approach that
should be used to QA a flow cytometer.
