Used in biomedical research to quantify levels of soluble tumor necrosis factor receptor I (sTNF-RI) in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit helps investigate inflammatory processes, immune system activation, and disease progression in conditions like rheumatoid arthritis, sepsis, Crohn’s disease, and other chronic inflammatory or autoimmune disorders. It is also applied in clinical research to evaluate the effectiveness of anti-inflammatory therapies and monitor biomarker changes associated with TNF signaling pathways.
