IPTG (Isopropil-β-D-tiogalactopiranósido) ≥99%, white powder

Proveedor: MP Biomedicals

Descripción: IPTG (isopropyl-β-thiogalactoside) is an analogue of allolactose that binds specifically to the repressor protein of the lac operon and induces expression of β-galactosidase in Escherichia coli.
IPTG is a commonly used reagent in cloning procedures that require induction of b-galactosidase activity and is used in conjunction with X-Gal in blue-white color selection of recombinant bacterial colonies.
The final concentration typically used in indicator plates is 0.2 mM.

X-Gal (5-Bromo-4-cloro-3-indolil-ß-D-galactopiranósido)

Proveedor: G-Biosciences

Descripción: X-gal (5-bromo-4-chloro-3-indolyl-β-D- galactopyranoside) is used to indicate whether bacteria express the ß-galactosidase enzyme, which is encoded by the lacZ gene. X-gal is cleaved by ß-galactosidase yielding galactose and 5-bromo-4-chloro-3-hydroxyindole, which is oxidised into 5,5'-dibromo-4,4'-dichloro-indigo, an insoluble blue product. Thus, if X-gal and an inducer of ß-galactosidase (usually IPTG) is contained within an agar medium on a culture plate, colonies which have a functional lacZ gene can easily be distinguished by their blue colour.

X-Gal (5-Bromo-4-cloro-3-indolil-ß-D-galactopiranósido) ≥98%, white powder para biología molecular

Proveedor: MP Biomedicals

Descripción: Storage: Store at -20 °C. Store Desiccated. Store Under Nitrogen. Protect from light.
5-Bromo-4-chloro-3-indolyl β-D-galactopyranoside, commonly known as X−Gal, is a histochemical substrate for β−galactosidase.
5-Bromo-4-Chloro-3-Indolyl-β-D-Galactopyranoside is used as indigogenic substrate for β-galactosidase, for detection of β-galactosidase-positive clones, and the identification of lac and bacterial colonies or phage plaques. It is the substrate of choice for blue-white selection of recombinant bacterial colonies with the lac+ genotype. X−Gal is cleaved by β−galactosidase to yield an insoluble blue precipitate. X−Gal is particularly useful in molecular biology applications to detect the activity of β−galactosidase which is frequently used as a reporter gene. In cloning, X−Gal is used to detect insertion of foreign DNA into the lacZ region of plasmid DNA using α-complementation which is based on vectors such as the pUC and the M13mp series that carry a fragment of the β-galactosidase gene encoding an α-fragment of β-galactosidase.
