Used in immunological research to quantify duck interleukin-1β levels in biological samples such as serum, plasma, or tissue homogenates. Enables study of inflammatory responses in avian species, particularly in poultry health and disease models. Supports research on immune system activation during infections, vaccination studies, and evaluation of anti-inflammatory treatments in ducks. Widely applied in veterinary diagnostics and avian immunology laboratories for sensitive and specific detection of IL-1β.
