Used to measure NAMPT (Nicotinamide Phosphoribosyltransferase) enzyme activity in human biological samples such as serum, plasma, or cell lysates. This kit is widely applied in research settings to study metabolic disorders, inflammation, and aging-related diseases. It enables quantification of active NAMPT protein levels, which plays a key role in NAD+ biosynthesis. Commonly used in studies related to diabetes, obesity, neurodegenerative diseases, and cancer to assess NAMPT as a potential biomarker or therapeutic target. The assay supports high-throughput screening and provides a reliable tool for monitoring changes in NAMPT levels under experimental or clinical conditions.
