Transferrin is an 80 kDa serum glycoprotein, which has an half-life of 8 to 10 days. The gene is located on human chromosome 3q22.1. Transferrin is expressed in hepatocytes.
Application
Biochem/physiol Actions
Transferrin facilitates the transfer of iron to erythron and peripheral tissues. Mutations in this gene is associated with atransferrinemia. Transferrin is required for fetal development. It is non immunogenic and transferrin-conjugated drugs inhibits cardiotoxicity and drug resistance.
Analysis Note
Purity by agarose electrophoresis.

HOW IS THIS PROTEIN PRODUCED AND WHAT IS THE REST 2% IMPURITY? THANKS!
1 answer-
This product is prepared by an ammonium sulfate precipitation process followed by a heat treatment and ion exchange chromatography purification. The specific details are considered proprietary. There is no treatment or handling during production that would be expected to cause deglycosylation of the protein. The residual impurities have not been identified. This product is tested for endotoxin and iron. Please see the Sample Certificates of Analysis: https://www.sigmaaldrich.com/certificates/Graphics/COfAInfo/fluka/pdf/PDF746107.pdf
