Effect of drug concentration on radioiron uptake from iron-loading medium.
Five-day-old cultures were first exposed to 0 to 320 μM deferoxamine (DFO) or ICL670A (ICL) and after 10 minutes. incubated with 160 μM59Fe-labeled ferric ammoniun citrate for 24 hours. Results expressed as percent or total cellular radioactivity in untreated controls. Each point represents the mean ± 1 SD of 6 cultures.
