Alkali Scientific NPG [p Nitrophenyl β D glucuronide], 250 Mg
NPG (p Nitrophenyl β D Glucuronide) is a widely used reagent for the detection of glucuronidase activity in biochemical assays. This substrate, when hydrolyzed by glucuronidase enzymes, releases a yellow-colored compound that can be quantified, making it ideal for enzyme activity measurements. NPG is commonly used in research on drug metabolism, liver function, and the role of glucuronidase in various biochemical processes. The 250 mg pack is well-suited for high-sensitivity assays and is an essential tool for laboratories studying the conjugation of glucuronides in both humans and animals. It’s also valuable in diagnostic assays for enzyme-linked immunosorbent assays (ELISA).
