WebFeb 27, 2024 · The pET system consists of three modules and can be induced with isopropyl-β-D-thiogalactopyranoside (IPTG), which drives the expression of the T7 RNAP by the LacI expression system . Next, the T7 RNAP transcribes any gene of interest from P T7 to extremely high levels, resulting in a high (recombinant) protein yield. WebHowever, our studies with the pET vector system indicates increased production with induction early in the stationary phase of growth (i.e OD600nm ~6-7) with little variation in …

WebNov 28, 2024 · Thus, the trend is valid for a broad range of induction conditions. While the optimal inducer concentration is 0.1 mM IPTG at 28 °C, it decreases at 34 and 37 °C to 0.05 mM IPTG. A transition area is visible at 30 °C, where 0.05 mM IPTG is preferable for early induction and 0.1 mM IPTG is better for later induction.
