Description and Specification


For Use With (Application) Blue/white colony screening to distinguish recombinant (white) from non-recombinant (blue) colonies (1); Induction of gene expression under control of the lac promoter.
Product Type IPTG Solution, ready-to-use
Quantity 10 x 1.5mL (Aqueous Solution: 100mM)

It inactivates the lac repressor and induces synthesis of beta-galactosidase, an enzyme that promotes lactose utilization. IPTG is used to induce expression of cloned genes under control of the lac operon. It is used in conjunction with X-Gal to determine the lac phenotype in blue/white colony screening.

Ready-to-use 100mM IPTG aqueous solution is non-toxic, stable, 0.22μm membrane-filtered, formulated for direct use in blue/white colony screening.
