PARP cleavage during CD437- and MM002-mediated apoptosis.

WSU-CLL and ALL-REH cells were seeded in 6-well plates as described in the legend to Figure 1. CD437 (panel A) or MM002 (panel B) (500 nM) or vehicle alone was added to the cells, and the cells were harvested at various times. Western blots were performed as described in “Materials and methods.”
