Dear Flowers,

I am a PhD student and doing flow cytometry on peripheral blood
from healthy women. So far I have done quite a few samples and all of them
are quite consistent in terms of results, for example CD3, CD4, CD8, CD14,
CD66b expression. The attached FSC/SSC plot (FSC-SSC -1 file) looks very
unusual to me as you can see most of the granulocytes are having low FSC and
I am wondering if anyone have come across with this earlier and would
appreciate any help/comments. First I thought that there might be some
problem with the machine, so I did an experiment on my own blood (FSC-SSC -2
file) just to make sure that FACS machine is working fine and indeed I found
the same reproducible result.

I sincerely hope that someone here will be able to help me out in
understanding what could be wrong here! Thank you all.


Best wishes
