Figure 2From: PYRROLO[1,2-b][1,2,5]BENZOTHIADIAZEPINES (PBTDs) induce apoptosis in K562 cellsTime-dependent DNA fragmentation. Cells were exposed to the indicated concentrations of synthetic compounds. Cells were harvested by centrifugation and DNA was extracted. The DNA fragments were separated on 1,8% agarose gel electrophoresis and visualized under ultraviolet. Cells were exposed to 10 μM PBTD-1 and PBTD-3 for 8,16, and 24 h.Back to article page
