Used in immunological research to quantify mouse interferon-λ3 (IFN-λ3) levels in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables researchers to study the role of IFN-λ3 in antiviral immune responses, particularly in mucosal and epithelial tissues. It is widely applied in studies related to viral infections, inflammation, and immune regulation, helping to assess cytokine production in mouse models. The assay provides high sensitivity and specificity, making it suitable for monitoring IFN-λ3 expression during experimental treatments, vaccine development, and disease progression studies involving the type III interferon system.
