Mean amount of cells per staining in % extracted from Fig 3.

PC3 or U87MG cells were treated with DRS B2 (2.5 μM). One hour after treatment cells where double stained with FITC-Annexin-V and 7-AAD and analyzed by flow cytometry. The cell viability of cells was observed by measuring the amount of Annexin-V and 7-AAD negative and positive cells. Results represent the mean ± SEM of 3 determinations of A-V-/7-AAD- = FITC-Annexin-V and 7-ADD negative; A-V-/7-AAD+ = FITC-Annexin-V negative and 7-AAD positive; A-V+/7-AAD- = FITC-Annexin-V positive and 7-AAD negative; A-V+/7-AAD+ = FITC-Annexin-V and 7-AAD positive.
