In vitro tumor cytotoxicity induced by high dosage of HQ. One hundred microliters of cells suspended in complete medium at a concentration of 2 × 104 cells/ml was seeded in a 96-well plate overnight and treated with different concentrations of HQ. After 24-h incubation, HQ cytotoxicity was determined by MTS assay. a COLO320, b K-Balb, c Hep3B, d Daudi cells.
