Caspase 3/7 activities at 24 h (IC50 = 262.5 μM), 48 h (IC50 = 190.3 μM), and 72 h (IC50 = 88.1 μM) of incubation times. EGCG concentrations used are based on respective IC50 for different incubation times. Caspase 3/7 activity at different times was measured in relative to the control sample. , , and .
