Used in biomedical research to measure levels of soluble interleukin-1 receptor type I in biological samples such as serum, plasma, or cell culture supernatants. This kit enables researchers to study inflammatory processes, immune responses, and related diseases including autoimmune disorders, sepsis, and chronic inflammation. It is commonly applied in preclinical studies, drug development, and disease monitoring where precise quantification of IL-1sRI helps assess immune system modulation. The assay supports high-throughput analysis and provides reliable data for understanding cytokine regulation and evaluating therapeutic interventions targeting the IL-1 signaling pathway.
