X-Gluc Dicyclohexylamine is a dye reagent for the detection of β-glucuronidase, an enzyme produced by Escherichia coli. X-Gluc sodium can be used to detect E. coli contamination in food, water and the urinary tract. X-Gluc sodium is also widely used in molecular biology experiments to label and detect the expression of target genes (GUS reporter system)^[1].

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
1. Dissolve 20 mg X-Gluc Dicyclohexylamine in 1mL dimethylformamide (DMF) to prepare X-Gluc master mix.
2. Add the prepared X-Gluc solution to agar medium plates at a final concentration of 50 μg/mL without sterilization.
3. Allow the plates to air dry and be used to inoculate the organisms.
4. Incubate the plates at 35°C and observe 16-24 h after inoculation.

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

* Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
