DNA cleavage.
(A) Large-scale DNA fragmentation does not occur in F3 and F4 cells committed to apoptosis after CD2 apoptotic induction but does occur in a BOC-D.fmk inhibitable manner. (B) F5 cells entered the execution phase. Genomic DNA from 2 × 106 cells of each Percoll fraction was analyzed by pulse-field gel electrophoresis.
