X-Gluc sodium is a dye reagent for the detection ofβ-glucuronidase(GUS), an enzyme produced byE. coli. X-Gluc sodium can be used to detectE. colicontamination in food, water and the urinary tract (GUSas a specific detection indicator). X-Gluc sodium is also widely used inmolecular biologyexperiments to label and detect the expression of target genes (reacts with theGUS gene, appears blue)^[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 sodium 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℃ and observe 16-24 h after inoculation.
