X-Gluc is a chemical compound with the molecular formula C14H13BrClNO7. It is used as a reagent to detect β-glucuronidase, an enzyme produced by the E. coli bacterium. It is used to detect E. coli contamination in food, water and the urinary tract. In addition, it is widely used in molecular biology experiments to mark and select the expression of target genes (GUS reporter system).
