Used to measure interferon-gamma (IFN-γ) levels in human biological samples such as serum, plasma, or cell culture supernatants with high sensitivity. This ELISA kit is commonly applied in immunology research to study T-cell responses, monitor cytokine production during infections, and evaluate immune activation in autoimmune diseases, cancer, and vaccine development. Its high sensitivity makes it suitable for detecting low concentrations of IFN-γ, which is critical in early immune response studies or when working with limited sample volumes. Widely used in clinical labs and research settings for accurate quantification of this key pro-inflammatory cytokine.
