On protein induction
WebUpon induction with IPTG, the lac repressors no longer bind to the lac operator region and T7 RNA polymerase is produced. This increased level of T7 RNA polymerase production exceeds the limited capacity of the few T7 lysozyme proteins present to inhibit T7 RNA polymerase, resulting in expression of the gene of interest. Webanalysis. Induction in bacteria can be performed using one of two basic methods: slow or fast induction. Fast induction will not work for all proteins and may give suboptimal …
