Representative data of double staining for annexin V-propidium iodide (PI) uptake from test groups and control by fluorescence activated cell sorting (FACS), after 48 hours of incubation. The percentage of PI-negative and annexin V-positive cells that were in early apoptosis, and PI positive and annexin V-positive cells that were dead or in end-stage apoptosis, are represented in each quadrant. (A) control, (B) 15 µM resveratrol (R), (C) 50 µM R, (D) 100 µM R, (E) 700 µM prednisolone (P), (F) 50 µM R+700 µM P. Ethanol, vehicle control.

Abbreviation: FL1-H, height in the FL1 channel.
