Used to quantitatively measure interleukin-23 (IL-23) levels in biological samples such as serum, plasma, or cell culture supernatants from mouse models. This kit is widely applied in immunology research to study inflammatory and autoimmune diseases, including multiple sclerosis, psoriasis, and inflammatory bowel disease, where IL-23 plays a key role in driving T-helper 17 (Th17) cell responses. It enables researchers to monitor changes in IL-23 expression under experimental conditions, assess the efficacy of therapeutic interventions, and understand cytokine regulation in disease progression. The assay provides high sensitivity and specificity, making it suitable for preclinical studies involving murine models of immune-mediated disorders.
