Used in research settings to detect and quantify porcine beta interferon (IFN-β) levels in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit is particularly valuable in immunology and virology studies involving swine, helping researchers assess immune responses during viral infections like porcine reproductive and respiratory syndrome virus (PRRSV) or influenza. It supports vaccine development and evaluation of antiviral therapies by providing a reliable measure of IFN-β production, a key marker of innate immune activation. The assay enables high-throughput analysis with high sensitivity and specificity, making it suitable for monitoring interferon dynamics in experimental models and disease investigations.
