Figure 3: Cell vitality and apoptosis induced by isorhamnetin.

(a) Effect of isorhamnetin on cell viability in K562 cells measured by CCK-8 assay after exposed to increased concentrations (0–200 μ M) for 48 h. (b) and (c) Cell apoptosis of isorhamnetin on K562 cells measured by Annexin V-FITC assay after exposed to increased concentrations (0–50 μ M) for 48 h. All data were shown as mean standard deviation (n = 6). Statistical significance was calculated by Student’s t-test.
