Cell viability studies with C₁₂-resazurin assay. BV2 cells were incubated for 4 and 24 h with different iron concentrations of SDIO. Fluorescent intensities reflecting fractional survival were normalized against the signal from the untreated cells. All error bars present standard error of the mean (SEM) ().
