KEMYSTERY is a supplier of 5-Bromo-4-chloro-3-indolyl-b-D-galactopyranoside (X-GAL) CAS 7240-90-6, a substrate used in the detection of b-galactosidase in bacteria. It is used in microbiology to test for the presence of an enzyme called beta-galactosidase and also used to detect activity of this enzyme in histochemistry and bacteriology. X-gal CAS 7240-90-6 is also used as a visual indication to check whether a cell expresses a functional Beta-galactosidase enzyme in a technique called blue/white screening. This method of screening is a good way of distinguishing a successful cloning product from the unsuccessful ones. KEMYSTERY manufactures and supplies X-gal CAS 7240-90-6 globally in custom packs from grams to multi kilos. For moire details please email on firstname.lastname@example.org.
