Used in immunological research to quantify mouse interferon-λ (IFN-λ) levels in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables researchers to study the role of IFN-λ in antiviral responses, inflammation, and immune regulation in mouse models. It is particularly useful in studies related to mucosal immunity, viral infections (e.g., hepatitis, influenza), and autoimmune diseases. The assay provides high specificity and sensitivity, allowing accurate measurement of cytokine production in response to pathogens or therapeutic interventions. Widely applied in preclinical research to evaluate immune responses and assess the efficacy of vaccines or antiviral drugs.
