Used in immunological research to quantify interleukin-23A levels in biological samples such as serum, plasma, or cell culture supernatants. Enables study of inflammatory responses and immune regulation, particularly in autoimmune diseases like psoriasis, inflammatory bowel disease, and multiple sclerosis. Supports evaluation of therapeutic interventions targeting the IL-23 pathway. Provides a reliable, sensitive, and specific method for detecting mouse IL-23A in preclinical animal models.
