Description

Beta-galactosidase inducer.Isopropyl-β-D-thiogalactoside is used as a reagent in molecular biology. It is used as an effective inducer of protein expression where the gene is under the control of the lac operator. It is used with 5-bromo-4-chloro-3-indolyl-beta-D-galactopyranoside to identify the non-recombinant plasmid in cloning experiments by blue-white screen methodology.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
