Used in immunological research to quantify sheep interleukin-1 levels in biological samples such as serum, plasma, or cell culture supernatants. Enables study of inflammatory responses in ovine models, supporting research in veterinary immunology, infectious disease progression, and vaccine development. Commonly applied in studies involving mastitis, respiratory infections, and autoimmune conditions in sheep. Provides a reliable, sensitive, and specific method for detecting IL-1 concentration, aiding in the assessment of immune activation and treatment efficacy in experimental settings.
