Comparison of viability between CHO and CHO/ΔNL cells following FeSO4 treatment. CHO and CHO/ΔNL cells were incubated in the absence (Control) or presence of different concentrations of FeSO4 (5–20 μM) for 24 h. Viability of the cell cultures was determined by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) method. The data are expressed as percent of Control. Representative curves from four independent experiments are shown. *P < 0.05; **P < 0.01 versus CHO cells.
