Used in immunological research to quantify rat interleukin-12 (IL-12/p70) levels in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables researchers to study the role of IL-12 in immune responses, including T-cell activation, Th1 differentiation, and cytokine regulation. Commonly applied in studies related to inflammation, autoimmune diseases, infectious diseases, and vaccine development. Provides a sensitive and specific method for monitoring IL-12 production in experimental models involving rats, supporting preclinical research in immunology and pharmacology.
