Used in immunological research to detect and quantify interleukin-6 levels in duck samples, particularly in studies related to avian immune responses, infectious diseases, and inflammation. Commonly applied in veterinary research, vaccine development, and monitoring of poultry health. Enables researchers to assess cytokine production during viral or bacterial infections such as avian influenza. Suitable for use with serum, plasma, or cell culture supernatants from ducks. Provides a reliable tool for understanding immune regulation in waterfowl and supports disease management in commercial and experimental flocks.
