Used in biomedical research to quantify adenosine deaminase (ADA) levels in biological samples such as serum, plasma, and cell culture supernatants. This kit is particularly valuable in immunology and oncology studies, where ADA activity is linked to immune system function and diseases like tuberculosis, HIV, and certain cancers. It enables high-throughput screening and precise measurement in clinical diagnostics and research settings, supporting the investigation of purine metabolism and immune response regulation.
