IPTG is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon.{22697} It is used in the concentration range of 100 μM - 1.5 mM to induce protein expression where the gene is under the control of the lac operator and is suitable for use with X-gal or bluo-gal to detect lac gene activity in cloning procedures.{24874}
