Rapid preparation of highly purified human transferrin

A rapid, two-step purification for human transferrin using DEAE-Sephacel chromatography followed by phenyl-boronate affinity chromatography is described. The method gives a 70% yield and isolates transferrin of over 97% purity which is hemopexin-free. The remaining protein is due to a single contaminant which may be the glycosylated form of albumin.
