Fig. 3From: Cytotoxic and apoptogenic effect of hypericin, the bioactive component of Hypericum perforatum on the MCF-7 human breast cancer cell lineFlowcytometery results for LD50 dose of cisplatin and hypericin in 24 h on MCF-7 cells. a Treatment of cells with 5 (μg/ml) concentration of hypericin showed 52 % apoptosis (right up quadrant shows cells in late apoptosis). b Treatment of cells with 20 (μg/ml) of cisplatin showed 60 % apoptosis (cells in right up quadrant are in late apoptosis)Back to article page
