Used in biomedical research to detect and quantify TRAIL-R3 levels in biological samples such as serum, plasma, and cell culture supernatants. Enables researchers to study the role of TRAIL-R3 in apoptosis regulation, cancer progression, and immune response. Commonly applied in oncology and immunology studies to evaluate the expression of decoy receptors involved in tumor cell survival. Supports high-throughput screening and biomarker validation in preclinical research. Provides a reliable and sensitive method for monitoring changes in TRAIL-R3 during therapeutic interventions.
