![Alkali Scientific X Glucoside [5 Bromo 4 Chloro 3 indolyl β D glucopyranoside], 100 Mg](https://assets.fishersci.com/TFS-Assets/CCG/product-images/5000661000.jpg-250.jpg)
Alkali Scientific X Glucoside [5 Bromo 4 Chloro 3 indolyl β D glucopyranoside], 100 Mg
X-Glucoside [5-Bromo-4-Chloro-3-Indolyl β-D-Glucopyranoside] is a chromogenic substrate used in microbiological and molecular biology assays to detect β-glucosidase activity. The 100mg pack is ideal for smaller-scale experiments or laboratories with specific enzyme testing needs. Upon hydrolysis by β-glucosidase, the substrate produces a blue color, which serves as a clear visual indicator of enzyme activity. X-Glucoside is commonly used in studies of carbohydrate metabolism, gene expression analysis, and microbiological testing to monitor the presence of β-glucosidase-producing organisms. This reagent is a valuable tool for enzyme assays, protein function studies, and diagnostic testing in molecular biology.
