Figure 6From: Sodium Ascorbate induces apoptosis in neuroblastoma cell lines by interfering with iron uptakeEffect of vitamin C on caspases activation. HTLA-230 and SH-SY5Y were treated with the indicated concentrations for 12 and 24 hours. After detachment, cells were stained with the pan-caspase-fluorescent-probe z-VAD-FMK according to the manufactures instructions. Relative increases in fluorescence emission were detected by single color flow cytometry. The data are the mean ± S.D. from three independent experiments.Back to article page
