Samples with moderate to low percentage apoptosis ran very slowly.
Samples with high percentage apoptosis ran much faster. Could the increase
in flow rate be due to fragments of nuclei being detected by the flow
cytometer?
I set the cytometer so that the G0/G1 peak fell at channel 250 (linear
scale) on the FL2-A plot. For analysis, I gated on the singlets from the
FL2-W vs. FL2-A plot.
Should I be thresholding on FSC instead of FL2? If I threshold on FSC,
where should the cut-off be? Any thoughts on the matter will be
appreciated.
Thanks!
