In vitro Transfer of Radiocadmium,CD 115,from Plasma to Human Erythrocytes. ∗

Abstract

Summary

The 24-hour in vitro transfer of radiocadmium, Cd¹¹⁵, from plasma to human erythrocytes was investigated. Most of the isotope became erythrocyte-bound during the first 8 hours of incubation although subsequent kinetics were somewhat obscured by hemolysis. The magnitude of the shift approximated 30% of total cadmium, although the erythrocytes of one subject, who had recently hemorrhaged, exhibited a much greater affinity for the metal. These findings suggest the desirability of further studies to determine the value of cadmium as an indicator of erythrocyte survival.
