Isopropyl β-d-1-thiogalactopyranoside (IPTG) is a molecular biology reagent. This compound is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce protein expression where the gene is under the control of the lac operator. WebJul 17, 2024 · From earliest days, basal expression prevented establishment of inducible strains for producing proteins that are stressful to the host. Newly developed pAL vectors now reduce basal expression to levels where coding sequences for even the most stressful proteins can be maintained and induced.
