Used in biomedical research to quantify soluble tumor necrosis factor receptor type II (sTNF-RII) levels in human serum, plasma, or cell culture samples. This ELISA kit enables researchers to study inflammatory processes, immune system activation, and disease mechanisms related to TNF signaling, such as rheumatoid arthritis, sepsis, and autoimmune disorders. It is commonly applied in clinical research and drug development to monitor biomarker changes and assess therapeutic efficacy.
