Interferon Alfa-2a is a recovery research peptide. Interferon Alfa-2a is an interferon alpha/beta receptor agonist used in the treatment of various neoplasms and viral infections.

Interferon Alfa-2a is a recombinant interferon classified as an interferon alpha/beta receptor agonist. It functions by binding to and activating interferon alpha/beta receptors, initiating a cascade of intracellular events that modulate immune responses and inhibit cell proliferation. Approved by the FDA in 1986, it is used for conditions such as neoplasms, including melanoma and renal cell carcinoma, and viral infections like Hepatitis C. Research has explored its use in combination therapies for myeloproliferative disorders such as polycythemia vera and essential thrombocythemia, particularly in patients resistant or intolerant to other treatments.
