Analysis Note

The specific activity was determined by the dose-dependent proliferation of WISH (heteroploid human amnion cell line) in presence of VSV ( vesicular stomatitis virus).

Biochem/physiol Actions

Interferon α 2B (IFN-α 2B) belongs to the type I interferon protein family. It is produced by many cell types in response to viral infection. IFN-α 2B has antiproliferative and antitumor activities, as well as induction of apoptosis and the inflammatory response. It enhances the expression of MHC proteins by increasing the presentation of antigen peptides and activates cytotoxic T-cells.

General description

The interferon α 2 (IFN-α2) exists in three forms 2a, 2b and 2c. It consists of 165 amino acids and five α helices. IFN-α2B is found structurally stable at pH 7. The recombinant IFN-α is nonglycosylated compared to the natural human IFN-α.
