Used in immunological research to quantify rabbit interleukin-2 (IL-2) levels in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables researchers to monitor T-cell activation and immune response in experimental models involving rabbits. It is commonly applied in studies of inflammation, vaccine development, autoimmune diseases, and infectious diseases where IL-2 plays a key regulatory role. The assay provides high sensitivity and specificity, allowing accurate measurement of IL-2 concentration to support data-driven conclusions in preclinical research.
