Lack of interaction of procaspase-2L with FADD and procaspase-8 in anti-Fas Ab–treated U937 cells.

Coimmunoprecipitation (IP) experiments from control (c) and anti-Fas Ab–treated (Fas; 6 hours) U937/neo cells were performed with anticaspase-2L or anticaspase-8 Abs. Western blot analysis was revealed with anticaspase-8 (A) and anti-FADD (B) Abs. Abs used to perform IPs were loaded as control (rAb and mAb).
