WebIPTG is added to a final concentration of 0.4 mM for induction of protein expression. Before the addition of IPTG, an aliquot of cell culture should be removed and incubated separately as an uninduced control (sample 1, uninduced). Initially induction at 37°C for 2-4 hours can be tested for expression and solubility. http://www.dentalearner.com/page/2

WebIPTG Induction Theory 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. Like … WebIPTG is added to a final concentration of 0.4 mM for induction of protein expression.
