Molecular biology reagent. Chromogenic substrate for beta-galactosidase. Used in gene cloning together with IPTG (Prod. No. bs-75001C) to indicate whether a cell expresses the beta-galactosidase enzyme, which is encoded by the lacZ gene, in a technique called blue/white screening. Distinguishes between recombinant and non-recombinant plasmids carrying the beta-galactosidase gene. Used in two-hybrid analysis. X-Gal is used to determine E. coli and coliform content in drinking water samples.
