Webfreezer stocks in parallel and use working stocks for an extended period. Auto-induction allows eﬃcient screening of many clones in parallel for expression and solubility, as cultures have only to be inoculated and grown to saturation, and yields of target protein are typically several-fold higher than obtained by conventional IPTG induction. 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.
