Transferrin is a single polypeptide chain glycoprotein. It is a member of the iron binding family of proteins. It has a molecular weight of 79.5kD and a serum concentration range of 1800-2700mg/L. It is synthesized in the liver. It consists of two domains each having a high affinity reversible binding site for Fe3+. The iron is transported in blood and interstitial fluids to sites of use and disposal. Iron/transferrin is essential in hemoglobin synthesis and for certain types of cell division. Serum concentration rises in iron deficiency and pregnancy. Serum concentration falls in iron overload, infection and inflammatory conditions. Applications: Suitable for use in ELISA and Western Blot. Other applications not tested.
