IFN-α 2a (GFH54-250)

Interferon-α 2a (IFN-α 2a) is a type I interferon made by leukocytes during viral infection. The JAK-STAT pathway mediates the antiviral and anti-cell proliferation activities of IFN-α 2a. IFN-α proteins are widely used as standard treatments during antiviral and antineoplastic therapies. The IFN-α 2a variant differs from IFN-α 2b by one amino acid.
