Used to quantitatively measure interleukin-38 (IL-38) levels in mouse biological samples such as serum, plasma, or cell culture supernatants. IL-38 is a member of the interleukin-1 family with anti-inflammatory properties, and its detection helps in studying immune regulation, inflammatory diseases, and autoimmune conditions in preclinical mouse models. The ELISA kit enables researchers to assess the role of IL-38 in disease progression or response to treatment by providing a sensitive and specific means to monitor cytokine expression. Common applications include research on arthritis, colitis, asthma, and other inflammation-driven pathologies.
