From: Basic Mechanisms of Arsenic Trioxide (ATO)-Induced Apoptosis in Human Leukemia (HL-60) Cells
Arsenic trioxide (ATO)-induced DNA fragmentation in HL-60 promyelocytic leukemia cells. Lane 1: M-molecular weight marker; lane 2: control with no ATO treatment; lane 3: 2 μg/mL; lane 4: 4 μg/mL; lane 5: 6 μg/mL; and lane 6: 8 μg/mL ATO. Twelve (12) μL of each sample was electrophoresed on a 1.2% agarose. DNA was stained with ethidium bromide and then visualized under UV light.
