Used in biomedical research to quantify levels of soluble TNFRSF1B in biological samples such as serum, plasma, and cell culture supernatants. This kit helps investigate inflammatory processes, autoimmune diseases, and cancer progression, as TNFRSF1B is involved in regulating immune responses and apoptosis. It is widely applied in clinical labs and pharmaceutical research to assess disease markers and monitor therapeutic efficacy in conditions like rheumatoid arthritis, Crohn's disease, and sepsis. The assay supports high-throughput screening and biomarker validation due to its sensitivity and specificity.
