Used to measure interleukin-15 (IL-15) levels in biological samples such as serum, plasma, or cell culture supernatants from mice. It is commonly applied in immunology research to study immune cell activation, proliferation of T cells and NK cells, and inflammatory responses. The kit helps in monitoring disease models involving autoimmunity, infection, and cancer in preclinical studies. Its high sensitivity and specificity make it suitable for detecting low concentrations of IL-15, enabling accurate assessment of cytokine dynamics in experimental conditions.
