Used to measure interleukin-2 (IL-2) levels in biological samples such as serum, plasma, or cell culture supernatants from mice. It is commonly applied in immunology research to study T-cell activation and immune responses. The kit helps evaluate cytokine production in experimental models of infection, autoimmunity, and cancer immunotherapy. Its high sensitivity and specificity make it suitable for quantifying low concentrations of IL-2 in small sample volumes. Widely used in preclinical studies to assess the effectiveness of therapeutic interventions on immune system modulation.
