Background. IPTG (isopropyl beta-D-thiogalactoside) Inducer for Beta-Galactosidase Expression acts as a molecular mimic of a lactose metabolite. The presence of IPTG triggers the activation of the lac operon for downstream gene transcription due to its binding the lac repressor.Due to the presence of a sulfur atom in IPTG, the cells cannot degrade the inducer and therefore its concentration remains constant.IPTG (isopropyl beta-D-thiogalactoside) Inducer for Beta-Galactosidase Expression is ideal for investigators in Immunology, Cell Biology, and Microbiology research.he presence of IPTG triggers the activation of the lac operon for downstream gene transcription due to its binding the lac repressor.
