Figure 1: Apoptosis induction by benzamide in K562 cells as detected by nuclear fragmentation and nucleosomal ladders. A: Typical picture representing the normal nuclei in untreated control cells; B: Apoptotic cells showing fragmented nuclei in cells treated with 5 mM benzamide for 48 h; C: Nucleosomal ladder obtained in K562 cells treated with 2.5 mM (lane 2), 5 mM (lane 3) and 10mM (lane 4) benzamide for 48 h. Lane 1 represents nucleosomal ladder in untreated control cells.
