Effect of IFN-γ and EPO on activation of caspase8.
Cells were incubated under the indicated conditions in serum-free medium for 16 hours. Cells were then incubated with fluorogenic caspase8 substrate IETDAFC for 1 hour at 37°C. The fluorescence intensity was then measured using a multilabel counter. The mean of triplicate studies is shown.
