(A) Gating strategy for imaging flow cytometry experiments shown for stimulation of HeLa-CD95 cells with 250 ng/ml CD95L followed by staining with anti-p65 antibodies as well as of the nucleus with the DNA dye 7AAD. For subsequent analysis, focused images of single cells are selected. Similarity of the p65 and 7AAD signals in the nucleus serves as readout for NF-B activation. (B) HeLa-CD95 cells were stimulated with 250 ng/ml CD95L for indicated times or with indicated doses of CD95L for 60 minutes. Cells were permeabilized Pyridoxal isonicotinoyl hydrazone and immunostained for p65, phospho-p65 and nucleus (7AAD) and analyzed with imaging flow cytometry for p65 translocation and p65 phosphorylation at Ser536.
