Used in immunological research to detect and quantify porcine lambda interferon (IFN-λ) in biological samples such as serum, plasma, or cell culture supernatants. This kit is particularly valuable in veterinary research and swine immunology studies, helping to assess antiviral responses, immune activation, and disease progression in pigs. It supports research on viral infections like porcine reproductive and respiratory syndrome virus (PRRSV) and swine influenza, where IFN-λ plays a role in mucosal immunity. The assay enables high-throughput analysis with high sensitivity and specificity, making it suitable for monitoring immune responses in vaccine development and pathogenesis studies.
