Invitrogen™ X-GlcU, CHA (5-Bromo-4-Chloro-3-Indolyl β-D-Glucuronide, Cyclohexylammonium Salt)

X-GlcU is a widely used chromogenic substrate for β-glucuronidase (GUS). It yields a dark blue precipitate at the site of enzymatic activity. X-GlcU is routinely used to detect GUS expression in transformed plant cells and tissues. X-GlcU can also be used to detect E. coli contamination in food and water
