Used in immunological research to detect and quantify duck interferon-gamma (IFN-γ) in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables researchers to study immune responses in ducks, particularly in the context of viral or bacterial infections. It is widely applied in veterinary research, vaccine development, and disease monitoring in poultry. The assay helps assess T-cell activity and cellular immunity, providing insights into the effectiveness of vaccines or the progression of infectious diseases like avian influenza or duck plague. Its high sensitivity and specificity make it a valuable tool for monitoring cytokine levels in experimental and diagnostic settings.
