Used in research to quantify soluble interleukin-6 receptor (sIL-6R) levels in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit helps study the role of sIL-6R in inflammatory diseases, autoimmune disorders, and cancer by enabling accurate measurement of receptor concentration. It supports investigations into IL-6 signaling pathways, particularly trans-signaling mechanisms involved in chronic inflammation and tissue damage. Commonly applied in immunology, oncology, and biomedical research settings to evaluate therapeutic targets and monitor disease progression.
