Used in biomedical research to quantify soluble Tumor Necrosis Factor Receptor 1 levels in human serum, plasma, or cell culture samples. Enables researchers to study inflammation, immune response, and disease progression in conditions such as rheumatoid arthritis, sepsis, diabetes, and autoimmune disorders. Widely applied in clinical labs and pharmaceutical development to evaluate therapeutic efficacy and monitor biomarker changes during treatment. Provides high sensitivity and specificity for accurate detection of sTNFR1, supporting reliable data in immunoassay-based studies.
