Used in biomedical research to detect and quantify soluble interleukin-1 receptor-like protein levels in human biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables researchers to study the role of sIL-1RL in inflammatory processes, immune regulation, and autoimmune diseases. It is particularly useful in clinical research settings investigating conditions like rheumatoid arthritis, sepsis, and other inflammatory disorders where interleukin-1 signaling pathways are involved. The assay provides a sensitive and specific method for monitoring biomarker changes in response to therapeutic interventions or disease progression.
