Figure 7. Caspase activity of toxin-treated cells: OE21 or OE33 cells were treated with increasing concentrations of mPA-EGF (gray, 0.1 nM to 100 nM) or mPA-ZHER2 (black, 0.1 nM to 100 nM) and a fixed concentration of LFN-C3 (8 nM) for 24 h, as indicated.

Lysates were prepared and tested for caspase 3/7 activity. Staurosporine was used as positive control.
