Used in immunological research to quantify interleukin-12 (IL-12) levels in biological samples such as serum, plasma, or cell culture supernatants. Enables researchers to study the role of IL-12 in immune responses, including T-cell activation and differentiation, particularly in the context of infections, autoimmune diseases, and cancer immunotherapy. Widely applied in preclinical studies to evaluate the efficacy and mechanism of immunomodulatory drugs. Supports high-throughput screening due to its reliable and sensitive detection method.
