Used for the quantitative measurement of interferon-alpha 2 (IFN-α2) in human biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit is widely applied in clinical research and immunology studies to assess immune responses, particularly in viral infections like hepatitis B and C, HIV, and autoimmune diseases such as systemic lupus erythematosus. It enables researchers to monitor cytokine levels during therapeutic interventions involving interferon treatments, helping evaluate drug efficacy and patient response. The assay is also useful in vaccine development and cancer research where IFN-α2 plays a role in antiviral and antitumor immunity.
