The sustained apoptotic effect of M3-p53-R12 protein on leukemia cells. (A) Leukemia cells were treated with M3-p53-R12 or M3-EGFP protein (10 μg/ml= 0.15 μM) on day 0 and harvested daily on day 1~ 3. The relative survival ratio of treated HL-60 (B), Jurkat (C), and K562 cells (D) on each day was determined with MTT assay.
