1 In serum from thalassemia major patients supplemented with 10 microM DFO, FO formation paralleled NTBI removal but never exceeded 50% of potentially available NTBI; approximately one third of NTBI was chelated rapidly but only 15% of the remainder at 20 h. Addition of DFP increased the magnitude of the slower component, with increments in FO formation equivalent to complete NTBI removal by 8 h. This shuttling effect was absent in serum from healthy control subjects, indicating no transferrin iron removal. Deferoxamine transferrin Homo sapiens
