RUG ®, Resorufin-beta-D-glucuronic acid methyl ester, Biosynth Patent: EP 2718458 and US 9127303

CAS: 1415487-42-1

Living cells of Escherichia coli can be reliably detected with media that contain a chromogenic or fluorogenic substrate for beta-glucuronidase (also termed β-D-glucuronidase), an enzyme that occurs almost exclusively in E. coli. RUG®, Resorufin-beta-D-glucuronic acid methyl ester is a highly sensitive chromogenic and fluorogenic indicator for E. coli. After removal of the methyl ester group by unspecific hydrolysis, orange colored product is cleaved by beta-glucuronidase in liquid media or on agar plates and yields an intense pink color. Red fluorescence is obtained upon excitation at 560-570 nm.Formally ER175455.
