WebDec 1, 2024 · Here, we constructed inducer-free expression vectors allowing the integration of the recombinant gene into the B. subtilis genome. These vectors carried strong promoters and their expression level in B. subtilis was comparable to that from high copy number replicative plasmids while expression in E. coli remained relatively low. When stored as a powder at 4 °C or below, IPTG is stable for 5 years. It is significantly less stable in solution; Sigma recommends storage for no more than a month at room temperature. IPTG is an effective inducer of protein expression in the concentration range of 100 μmol/L to 3.0 mmol/L. Typically, a sterile, filtered 1 mol/L solution of IPTG is added 1:1000 to an exponentially growing bacterial culture, to give a final concentration of 1 mmol/L. The concentration used depends on t…

WebMay 10, 2024 · Isopropyl β-D-1-thiogalactopyranoside (IPTG, also known as lad-y) 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 E.coli protein expression where the gene is under the control of the lac operator. WebTo stimulate this process, the inducer IPTG can be added to the system. IPTG is a reagent which mimics the structure of allolactose, and can therefore bind to the lac repressor and prevent it from inhibiting gene expression.
