NHEM were exposed to 250 J/cm2 IRA, 0.40 J/cm2 UVB or
simultaneously to IRA+UVB. After 24 hours cells were harvested, permeabilized,
stained with antibodies against CD-95, BID, FLIPL and Bcl-2 and
subjected to FACS analysis. Histograms show fluorescence intensity (x
axis) versus cell number (y axis). Percentages
indicate positive cells. For each protein one representative experiment is
shown.
