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 Temperature: -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.
