Used in biomedical research to detect and quantify soluble Rabbit TRAIL-R3 levels in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit is specifically designed for studying the regulation of apoptosis in rabbit models, particularly in cancer and inflammatory diseases. It enables researchers to investigate the role of TRAIL-R3, a decoy receptor that modulates the TRAIL-induced apoptosis pathway, in immune response and tumor progression. The assay provides a reliable and sensitive method for monitoring changes in TRAIL-R3 concentration under experimental conditions, supporting preclinical studies in immunology and oncology.
