Used in biomedical research to measure soluble tumor necrosis factor alpha receptor levels in biological samples such as serum, plasma, or cell culture supernatants. This kit enables researchers to study inflammatory processes, immune system regulation, and disease mechanisms related to chronic inflammation, autoimmune disorders, and cancer. It is commonly applied in preclinical studies, clinical diagnostics research, and therapeutic monitoring where TNFα pathway activity is investigated. The assay helps evaluate the efficacy of anti-inflammatory drugs and biologics targeting the TNF signaling pathway.
