Sarcosine oxidase is widely used in biochemical research and clinical diagnostics, particularly for the measurement of sarcosine levels in biological samples. This enzyme plays a key role in enzymatic assays designed to detect and quantify sarcosine, which is a biomarker for certain metabolic disorders, including prostate cancer. In clinical settings, sarcosine oxidase is employed in automated analyzers to provide accurate and reliable results for patient samples. Additionally, it is utilized in the development of biosensors for real-time monitoring of sarcosine concentrations, aiding in early disease detection and monitoring. Its application extends to research studies focused on understanding metabolic pathways and the role of sarcosine in various physiological and pathological processes.
