NPG (p Nitrophenyl β D Glucuronide) is a high-purity reagent used for the detection and quantification of glucuronidase activity in various biochemical assays. This substrate, when hydrolyzed by glucuronidase enzymes, generates a yellow-colored product that can be easily measured. NPG is frequently used in pharmacological research, clinical diagnostics, and enzyme activity profiling, particularly in studies on drug metabolism and liver function. The 50g pack ensures a large supply for high-volume assays, making it suitable for large-scale research or diagnostic testing. This reagent is crucial for research on glucuronide conjugation in the liver and other tissues.
