Used to quantitatively measure interleukin-27 p28 (also known as IL-30) in biological samples such as serum, plasma, or cell culture supernatants from mice. This assay is particularly useful in immunology research for studying the role of IL-27 in T-cell activation, differentiation, and regulation of inflammatory responses. It helps investigate autoimmune diseases, infectious diseases, and cancer immunotherapy by providing accurate levels of this cytokine, which has both pro- and anti-inflammatory properties. The kit enables high-throughput analysis with high sensitivity and specificity, supporting detailed cytokine profiling in mouse models.
