Background Information

Interferon alpha-2a (IFN-α2a) belongs to the type I interferon family and possesses antiviral, antitumor, and immunomodulatory functions. This protein is encoded by the IFNA2 gene and is one of the human interferon alpha subtypes, with a conserved region located between amino acids 115–151. IFN-α2a plays a significant role in the response to viral infection and is an important tool molecule in immunology and cell biology research.
