title: Iron removal from transferrin by a cell-free amphibian system.
abstract: 1. Transferrin-bound iron was released by a cell-free solution prepared from Rana catesbeiana immature erythrocytes, showing that cellular integrity is not necessarily a requirement for this process as previously thought. 2. The biological molecule(s) involved in the removal of iron from transferrin is relatively small.
