X-Gluc Cyclohexylammonium Salt (XGLUC)
5-Bromo-4-chloro-3-indolyl-ß-D-glucuronide cyclohexylammonium salt; X-Gluc, Cha SALT; X-Glucuronide; X-GlcA

Indigo-blue chromogenic substrate used in the detection of beta-glucuronidase (GUS fusion marker) in E. coli for transcription and translation studies. Additional applications include bacterial contamination testing in water, meat, dairy, shellfish.

The chromogenic substrate X-Gluc is used in a variety of applications for the detection of the B-glucuronidase enzyme. Upon reduction, X-Gluc produces a localized color, making it useful in identifying GUS gene presence in most cell types1 and for the detection of the GUS gene fusion marker in plants. X-Gluc has reported applications in the detection of contaminated food samples such as meat, dairy, and shellfish products. X-Gluc also has clinical applications in the assessment of urinary tract infection by d etecting the pr esence of E. coli. It has gained international acceptance as an accurate indicator for the presence of E. coli in potable water samples b y reducing false positives and negatives found with traditional methods.
