Description
- IPTG (isopropyl-beta-D-thiogalactopyranoside) is a highly stable synthetic analog of lactose
- 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 (#R0941) to determine the lac phenotype in blue/white colony screening

- 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.
