Summary A low molecular weight complex of an iron oligomer (Mr ~ 1000) has been isolated from rat liver and characterized physically and chemically. The h.p.l.c.-purified material contains the free amino acids glutamate and aspartate. Chemical techniques suggest the iron present in the factor is as iron(III) and is readily donated to high-affinity chelators such as the hydroxypyridinones and desferoxamine.
