X-Gluc is a chromogenic substrate used in various applications for detecting X-glucuronidase. Upon reduction,X-Gluc produces localized color,aiding in the identification of the presence of the GUS gene in most cell types and detecting GUS gene fusion markers in plants.

X-Gluc is applied in the detection of Escherichia coli. The chromogenic substrate X-Gluc is used for various applications in detecting β-glucuronidase; an enzyme produced by Escherichia coli. Upon reduction, X-Gluc produces localized color, aiding in the identification of the presence of the GUS gene in most cell types and detecting GUS gene fusion markers in plants.

X-Gluc is utilized in identifying contaminated food samples such as meat, dairy products, and shellfish.

Its clinical applications extend to assessing urinary tract infections by detecting the presence of Escherichia coli. Internationally recognized as an accurate indicator of the presence of Escherichia coli in drinking water samples, X-Gluc helps reduce false positives and false negatives compared to traditional methods.
