Studies on plasma iron in the rat. I. Investigations in vitro on iron binding

    Research output: Contribution to journalArticlepeer-review


    The binding of iron to protein in rat plasma was investigated using Fe59 as tracer. Paper electrophoresis studies showed that the iron was bound only to the β-globulin fraction and that none was bound to albumin at iron concentrations of 29-2860 μg./100 ml. plasma. The iron-protein complex was not precipitated either by 22% sodium sulfate solution or by 42% sodium sulfite solution, both reagents being commonly used for precipitating the globulins of human plasma. The complex was precipitated, however, by 60% saturation of the plasma with ammonium sulfate solution. Precipitation studies with this reagent indicated that the binding of iron to protein was maximal above pH 6.4 and fell rapidly below this value. © 1961.
