Purification of folate binding factor in normal umbilical cord serum

Proceedings of the National Academy of Sciences of the United States of America

B Kamen, J D Caston

PMID: 676

Abstract

Human umbilical cord serum was found to contain both free folate and folate complexed to a high-molecular weight factor. The complexed folate was bound to a very high affinity binder and was present in concentrations equivalent to as much as 60 ng of 5-methyltetrahydrofolic acid per ml ...read more
