Interferon-alpha 2a (IFNα 2a) is a Type I interferon made by leukocytes during viral infection. It has anti-viral and non-proliferative activity induced by JAK1-STAT signaling. IFN-alpha 2s are the most widely used type for therapeutic purposes. IFNα 2b is a variant of IFNα 2a that differs by one amino acid. Recombinant human IFNα 2a is a non-glycosylated protein, containing 166 amino acids, with a molecular weight of 19.37 kDa.
