[Cytometry] Cell cycle of activated human PBMC

Dear Marjan,
	In my experience naive human T-cells show little detectable cell division, they must zip through the cell cycle very quickly, in this scenario even at 3 days there is little detectable cell division by this method, so I am not surprised by your result. I guess CFSE proliferation gives you more usable results given that the S phase & G2m percentages are at any one time point very low.

Hope this suggestion helps

Dear All,
I'm working with human PBMC, activated by 2µg/ml CD3/CD28 mAb. I've
performed cell cycle analysis after 24h activation on these cells and I've
got strange histograms! didn't see S phase! I have no idea about the
populations in FSC/SSC dot plot; I can see 3 populations, where I should
gate cells? What is the problem with this test?
Please see attached file. Any suggestion and comment would be greatly

Looking forward your kind reply
