Used in biomedical research to quantify levels of soluble TNFRSF1A in biological samples such as serum, plasma, and cell culture supernatants. This kit helps investigate inflammatory processes, immune system activation, and disease mechanisms linked to TNF signaling, including rheumatoid arthritis, inflammatory bowel disease, and certain cancers. It supports drug development and monitoring treatment responses by providing a reliable method to assess biomarker levels in clinical and preclinical studies.
