WebIsopropyl-β-D-thiogalactopyranoside (IPTG) is frequently used as an inducer of the lac operon for physiological work. IPTG binds to repressor and inactivates it, but is not a substrate for β-galactosidase. One advantage of … WebAug 6, 2015 · IPTG inducible system has been widely used for recombinant protein expression in E. coli. Its components like lac promoter, lac operator, lac repressor and their variants have been employed along with T7 or …

WebSep 16, 2015 · The IPTG induced culture contained 1.3 mg of YidC-GFP per liter and the non-induced culture contained 8.7 mg of YidC-GFP per liter [ 22 ]. The total membrane fractions isolated from the IPTG induced culture and from the non-induced culture contained 0.4 and 1.7 mg of YidC-GFP, respectively [ 22 ]. binding prayer catholicWhen 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.
