Used in immunological research to detect and quantify duck interferon alpha (IFN-α) in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables researchers to study the avian immune response, particularly in the context of viral infections in ducks, including duck hepatitis virus or avian influenza. It supports monitoring of IFN-α production during experimental infections, vaccine development, and evaluation of antiviral therapies in waterfowl. The assay provides a sensitive and specific means to assess innate immune activation in ducks, contributing to veterinary diagnostics and poultry health research.
