Used in veterinary research and diagnostic laboratories to detect and quantify porcine alpha interferon levels in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit is essential for studying immune responses in pigs, particularly during viral infections like swine fever, porcine reproductive and respiratory syndrome (PRRS), or influenza. It supports vaccine development and evaluation by measuring interferon production as an indicator of innate immune activation. The assay provides a reliable, sensitive, and high-throughput method for monitoring antiviral responses in swine health studies.
