General description

5-Bromo-4-chloro-3-indolyl α-D-glucopyranoside, X-Gluc, is a indigogenic substrate for β- glucuronidase enzyme (GUS). It aids screening of transgenic plants based on GUS activity. GUS deesterifies X-Gluc into indoxyl derivative which upon oxidative polymerization results in the generation of blue indigotin dye.

Application

suitable as substrate for α-glucosidase; substrate used in the Druggan-Forsythe-Iversen medium (DFI agar) for the selective detection of Enterobacter sakazakii in infant milk

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
