Used to quantitatively measure interleukin-27 (IL-27) levels in mouse biological samples such as serum, plasma, cell culture supernatants, and tissue homogenates. IL-27 is a cytokine involved in regulating immune responses, particularly in the differentiation and function of T cells. This kit is widely applied in immunology research to study inflammatory diseases, autoimmune conditions, and host defense mechanisms. It enables researchers to monitor IL-27 expression in experimental models of diseases like multiple sclerosis, colitis, and infections, helping to evaluate the effectiveness of therapeutic interventions targeting the immune system. The assay provides high sensitivity and specificity, making it suitable for detecting low concentrations of IL-27 in small sample volumes.
