DNA fragmentation in human leukemia (HL-60) cells exposed to garlic extract (GE) at 0 mg/mL (control with no GE treatment), 2 mg/mL, 4 mg/mL, 6 mg/mL, 8 mg/mL, and 10 mg/mL GE. M denotes the molecular weight marker. Twelve (12) μL of each sample was electrophoresed on a 1.2% agarose as described in Materials and Methods. DNA was stained with ethidium bromide and then visualized under UV light.
