Used in biomedical research to quantify soluble tumor necrosis factor receptor II (sTNFR-II) in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables researchers to study inflammatory processes, immune system activation, and disease progression in conditions like rheumatoid arthritis, sepsis, diabetes, and chronic inflammatory diseases. It is also applied in clinical research to evaluate biomarkers related to autoimmune disorders and response to therapeutic treatments targeting the TNF signaling pathway. The assay provides high sensitivity and specificity, making it suitable for monitoring sTNFR-II levels in large-scale studies and drug development.
