Figure 6
Effect of wild-type or R77Q Vpr on caspase-3 and DFF. Jurkat T cells were treated overnight with wild-type or R77Q (mutant) Vpr and analyzed for (a) caspase-3 activity and (b) DFF cleavage. Blots were stripped and reprobed for proliferating cell nuclear antigen (PCNA) to ensure equal loading (data not shown).
