Used in immunological research to quantify chicken interleukin-3 (IL-3) levels in biological samples such as serum, plasma, or cell culture supernatants. Enables study of immune responses in poultry, particularly in understanding hematopoiesis, inflammation, and T-cell mediated immunity. Widely applied in veterinary research, vaccine development, and disease monitoring in avian species. Supports investigation of cytokine networks in infectious diseases like avian influenza, Newcastle disease, and coccidiosis. Provides a reliable, sensitive, and specific method for detecting IL-3 to assess immune activation and evaluate therapeutic interventions in poultry health studies.
