Used in biomedical research to quantify levels of extracellular 5'-nucleotidase (CD73) in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit enables researchers to study the role of NT5E in immune regulation, cancer progression, and adenosine metabolism. It is particularly valuable in immunology and oncology studies where modulation of the adenosine pathway impacts T-cell function and tumor microenvironment. The assay supports high-throughput analysis with high sensitivity and specificity, making it suitable for preclinical evaluation of therapeutic targets and biomarker discovery.
