Evaluation of new medium with chromogenic substrates for members of the family Enterobacteriaceae in urine samples.

H Kodaka et al.

Journal of clinical microbiology, 33(1), 199-201 (1995-01-01)

A new medium containing 5-bromo-4-chloro-3-indolyl-beta-D-glucuronide cyclohexylammonium salt (Glu agar) for Escherichia coli and a new medium containing 5-bromo-3-indolyl-beta-D-galactoside (Gal agar) for beta-galactosidase-positive members of the family Enterobacteriaceae were compared with MacConkey agar in a diagnostic trial with 3,562 urine specimens.

[Determination of beta-galactosidase activity on nitrocellulose plates using 5-bromo-3-indolyl-beta-D-galactopyranoside and tetrazolium salts].

A N Markarian et al.

Bioorganicheskaia khimiia, 13(2), 263-265 (1987-02-01)

A simple and convenient technique has been developed for detection of beta-galactosidase from E. coli on nitrocellulose sheets using a mixture of 5-bromoindol-3-yl-beta-D-galactopyranoside and nitro blue tetrazolium, which enables rapid detection of fmole (10(-15) mole) quantities of the enzyme at

Cellular transformation of mouse embryo fibroblasts in the absence of activator E2Fs.

Tushar Gupta et al.

Journal of virology, 89(9), 5124-5133 (2015-02-27)

The E2F family of transcription factors, broadly divided into activator and repressor E2Fs, regulates cell cycle genes. Current models indicate that activator E2Fs are necessary for cell cycle progression and tumorigenesis and are also required to mediate transformation induced by
