Figure Lengend Snippet: RIPA protein extracts were prepared 4h or 18h after treatment of BJAB cells or BJAB K5F cells with ⍺Fas (10 ng/ml) and run on western blots and analyzed for, (A) caspase-8 and cleaved caspase-8, (B) Caspase-3 and cleaved caspase-3, (C) the cleaved form of PARP (89 kDa) and (D) procaspase 6. Signal intensity of each protein of interest was normalized with respect to β-actin and the value is displayed under each blot. Signal intensity of each protein with respect to β-actin and normalized to lane 1 is displayed under each blot. (E) An 18h experiment was done with ⍺Fas treatment without or with IDN-6556 (10 µM) caspase inhibitor (labeled I/⍺Fas) and then analyzed for procaspase-6. The relative levels of procaspase-6 are shown after normalizing to β-actin.
