Figure 7From: Sodium Ascorbate induces apoptosis in neuroblastoma cell lines by interfering with iron uptakeEffect of sodium ascorbate on single caspases activation. HTLA-230 and SH-SY5Y were incubated in the absence (0 mM) or presence of the indicated concentrations for 16 hours and then analyzed for single caspases by flow cytometry as described in Material and Method. Coloums, mean of three different experiments, each done in triplicate; bars, SD.Back to article page
