---|---|---|---|
Untreated | Anti-CD95 | Anti-CD95+ DEVD-FMK | |
HS445 | 7.5% | 20.5% | 9.9% |

*1 × 106 cells were untreated or treated with 500 ng/ml anti-CD95 mAb (CH11) for 72 hours with or without pretreatment with 10 μM caspase-3 peptide inhibitor, DEVD-FMK. Apoptosis was quantitated by TUNEL staining as described in Materials and Methods.
