Background Interferon-alpha 2b (IFNα 2b) 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-alphas are the most widely used type for therapeutic purposes. IFNα 2b is a variant of IFNα 2a that differs by one amino acid.
