Used for the quantitative measurement of interferon-beta (IFN-β) 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 diseases like multiple sclerosis where IFN-β levels are monitored during therapy. It enables researchers to evaluate the expression and secretion of IFN-β in response to viral infections, autoimmune conditions, and treatment with immunomodulatory drugs. The assay provides high sensitivity and specificity, making it suitable for detecting low concentrations of IFN-β in small sample volumes. It is also used in vaccine development and antiviral drug research to study the innate immune response.
