Figure 4. Caspase-3 like activity in mesophyll protoplasts under the expression of Cyt f.

Protoplasts were treated with Dex or ethanol for different times, and equal amount of cytosolic fractions were incubated with Ac-DEVD-AMC. The AMC fluorescences were measured by a Microplate reader at 30°C. The RFU/mg was relative fluorescence units per mg protein.
