Used in biomedical research to detect and quantify levels of TRAIL-R1, a receptor involved in apoptosis signaling, in biological samples such as serum, plasma, and cell lysates. This ELISA kit enables researchers to study the role of TRAIL-R1 in cancer development, immune regulation, and response to therapeutic agents. It is particularly valuable in oncology and immunology studies where understanding apoptotic pathways can inform drug development and disease mechanisms. The assay provides a sensitive and specific method for monitoring changes in TRAIL-R1 expression under experimental conditions, supporting both basic research and preclinical evaluation.
