Used for the quantitative measurement of human interleukin-1 receptor 2 (IL-1R2) in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit is widely applied in immunological research to study the regulation of inflammatory responses, as IL-1R2 acts as a decoy receptor that modulates IL-1 signaling. It is particularly useful in studies related to chronic inflammation, autoimmune diseases, and immune system regulation. The kit enables researchers to assess IL-1R2 levels in clinical samples, supporting biomarker discovery and evaluation of therapeutic interventions targeting the IL-1 pathway.
