[5-Bromo-4-chloro-3-indolyl-β-D-galactoside]


PR1MA X-GAL [5-Bromo-4-chloro-3-indolyl-β-D-galactoside]

Common Name: 5-Bromo-4-chloro-3-indolyl-β-D-galactoside
CAS Number: 7240-90-6
Molecular Weight: 408.6
Chemical Formula: C14H15BrCINO6
Solubility: DMSO and DMF
Storage Temp: -20°C

Chromogenic substrate of β-Galactosidase used in combination with IPTG for detection of β-Galactosidase activity in bacterial colonies. X-GAL is cleaved at the B1-4 bond between galactose and the 5-Bromo-4-chloro-3-indolyl portion of X-GAL by β-Galactosidase via hydrolysis. The cleavage of X-GAL results in the production of a water insoluble blue dichloro-dibromo-indigo precipitate. In cloning strategies with vectors such as Lambda-11, M13mp18 and 19, pUC18 and 19, pUR222 the E. coli lacZ gene is transformed to lac+ cells. After transformation the cells show β-Galactosidase activity in the presence of media containing X-GAL and IPTG. The insertion of a DNA fragment into the cloning sites of the lacZ gene results in the disruption of β-Galactosidase activity leading to the appearance of white colonies. Non-recombinant cells produce a blue indigo dye.

Produced by Streptomyces verticillus and part of the structurally related group of Bleomycin/Phleomycin type antibiotics. Used as a selective agent in transformation experiments with mammalian cells, plant cells, and yeast. Cytotoxic action of this type of antibiotic results from the ability to cause fragmentation of DNA. In Vitro studies indicate that Phleomycin causes the accumulation of cells in the G2 phase of the cell cycle.
