Sub. for beta-Glucuronidase

Detection of ß-Glucuronidase activity is widely used to identify E. coli bacteria contamination in food and water. The enzyme, which is encoded by GUS gene, is also frequently used as a reporter gene in plants. Biotium offers three chromogenic glucuronidase substrates, X-GlcU, Red-ß-D-gal and Rose-ß-D-gal, each of which yields a blue-, red- and pink-colored precipitating product respectively. The red and pink colors may be easier to detect than the dark blue color of X-GlcU product in plant cells. Biotium also offers the popular fluorogenic ß-glucuronidase substrate MUG for ultra sensitive detection.
