Interferon alpha 2b Human, E. coli Recombinant Protein

Description Interferon alpha 2b Human, E. coli Recombinant Protein is a single, non-glycosylated, polypeptide chain containing 166 amino acids and has a molecular mass of 19400 Dalton. The difference between IFNA2A and IFNA2B is in the amino acid present at position 23. IFN-alpha 2a has a lysine at that position 23 while IFN-alpha 2b has arginine. The IFN-alpha 2b gene was obtained from human leukocytes. The IFN-a 2b protein is purified by proprietary chromatographic techniques. Summary IFN-alpha is produced by macrophages and has antiviral activities. IFN stimulates the production of two enzymes: protein kinase and an oligoadenylate synthetase.
