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).


10 μg in glass bottle

Preparation Note

HumanKine IFN-α 2A, expressed in human HEK 293 cells, is a glycosylated monomer with an apparent molecular mass of 16 kDa. Production in human HEK 293 cells offers authentic glycosylation. Glycosylation contributes to stability in cell growth media and other applications.

Biochem/physiol Actions

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