Figure 4.
Western blotting analysis of the full length and cleaved caspase-3 activities following 48h incubation of RK33 and TE671 cells with either culture medium alone (control) or imperatorin (IMP) (10–100 µM). β-actin was used as a gel loading control. The right panel shows representative blots; the left panel shows a densitometry analysis of the bands.
