Iron Uptake from Rat Plasma Transferrin
iron release between fast and slow diferric transferrins and between fast and slow monoferric transferrins when incubated with reticulocytes or injected in vivo showed no significant difference in the behavior of the two isotransferrin species. Reticulocyte uptake of diferric transferrin resulted in the removal of both iron atoms from the transferrin molecule. A twofold greater iron uptake was ...
متن کاملIron uptake from rat plasma transferrin by rat reticulocytes.
Fast and slow rat transferrins were isolated by isoelectric focusing and prepared in their di- and monoferric forms. A comparison of the rates of iron release between fast and slow monoferric transferrins when incubated with reticulocytes or injected in vivo showed no significant difference in the behavior of the two isotransferrin species. Reticulocyte uptake of diferric transferrin resulted i...

متن کاملIntact transferrin receptors in human plasma and their relation to erythropoiesis.
Intact transferrin receptor molecules complexed with transferrin were found in human plasma. The concentration of receptors was determined by an enzyme-linked immunosorbent assay that uses polyclonal antibodies. The mean concentration of 8,279 micrograms/L in 56 normal adults appears to be unrelated to age or sex. Additional receptor measurements were performed on plasmas from 260 subjects with...
متن کاملTransferrin receptors in rat brain: neuropeptide-like pattern and relationship to iron distribution.
We have characterized and visualized the binding of 125I-labeled transferrin to sections of rat brain. This saturable, reversible, high-affinity (Kd = 1 X 10(-9) M) binding site appears indistinguishable from transferrin receptors previously characterized in other tissues. Moreover, a monoclonal antibody raised to rat lymphocyte transferrin receptors could immunoprecipitate recovered intact tra...
