Used in immunological research to quantify rabbit interleukin-3 (IL-3) levels in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables researchers to study immune system activation, hematopoiesis, and inflammatory responses in rabbit models. It is particularly useful in preclinical studies involving immune modulation, vaccine development, and infectious disease research where monitoring cytokine expression is critical. The assay provides high sensitivity and specificity, allowing accurate measurement of IL-3 concentration to support data-driven conclusions in biomedical experiments.
