Used to measure levels of Interleukin-25 (IL-25) in biological samples such as serum, plasma, or cell culture supernatants. This kit is primarily used in immunology and inflammation research to study the role of IL-25 in type 2 immune responses, allergic diseases like asthma, and parasitic infections. It enables researchers to quantify IL-25 protein expression in experimental models, supporting studies on cytokine regulation, immune cell activation, and development of therapeutic interventions targeting the IL-25 pathway. The assay is widely applied in preclinical research and biomarker discovery.
