Used in biomedical research to quantify levels of TRAIL protein in biological samples such as serum, plasma, and cell culture supernatants. This kit enables researchers to study the role of TRAIL in apoptosis, immune regulation, and cancer development. It is widely applied in oncology and immunology studies to evaluate TRAIL expression under various experimental conditions, including drug treatments and disease states. The assay supports high-throughput screening and biomarker discovery due to its sensitivity and reproducibility.
