4-Nitrophenyl β-D-Glucopyranoside is a chromogenic substrate used in enzyme assays to detect β-glucosidase activity. The 50g pack is ideal for high-throughput laboratories and large-scale experiments. Upon hydrolysis by β-glucosidase, this substrate produces a color change, which is easily measured to determine enzyme activity. This substrate is used in a variety of studies, including research on carbohydrate metabolism, enzyme kinetics, and microbiological analysis. It also serves as an important tool in diagnostic tests that monitor β-glucosidase activity in clinical and research applications, offering reliable results with minimal complexity.
