From: Sodium Ascorbate induces apoptosis in neuroblastoma cell lines by interfering with iron uptake

Sodium ascorbate induces apoptosis in neuroblastoma cell lines. Cells were seeded in six well plates and treated for 6 or 24 hours with increasing concentrations of sodium ascorbate. For each bar group, the concentration was: 0 mM (control), 0.5 mM, 1 mM, 2 mM, 3 mM. Cells were then processed and stained with propidium iodide as described in "Materials and Methods". The percent of cells in the sub-G1 phase of the cell cycle were considered apoptotic. The data are the mean ± S.D. from three independent experiments.
