Molecular biology reagent. beta-Galactosidase activity inducer in several bacteria, by binding and inhibiting the lac repressor. Used in gene cloning together with X-Gal (Prod. No. AG-CC1-0003), in a technique called blue/white screening. Distinguishes between recombinant and non-recombinant plasmids carrying the beta-galactosidase gene. Plant origin, contains no animal-derived contaminants. Stimulates beta-galactosidase in cellular systems in which dioxane would disrupt normal cell function.
