Bl 2iptg induction

WebIPTG induction is a longstanding technique in molecular biology. In this article, you’ll take a deep dive into this important application. You will learn what IPTG is, what induction is, who the main characters are, IPTG’s role in induction and … WebIPTG is a structural mimic of lactose (it resembles the galactose sugar) that also binds to the lac repressor and induces a similar conformational change that greatly reduces its affinity for DNA. Unlike lactose, IPTG is not part of any metabolic pathways and so will not be broken down or used by the cell.
