WebIPTG is an effective inducer of protein expression in the concentration range of 100 μM to 1.0 mM. Concentration used depends on the strength of induction required, as well as the genotype of cells or plasmid used. If lacIq, a mutant that over-produces the lac repressor, is present, then a higher concentration of IPTG may be necessary. WebMay 25, 2024 · IPTG was added for the full induction of DSD genes. The MG1655 ∆ aroE P lacUV5-asbF strain produced only 0.2 g/L of 3,4-DHBA in the presence of IPTG. MG1655 ∆ aroE P lacUV5-qsuB and MG1655 ∆ aroE P lacUV5-qa-4 strains accumulated ~2.7 g/L when IPTG was added and ~1 and 2 g/L of 3,4-DHBA without IPTG induction. This was due to …

WebSample Induction Protocol(for reference only) 1. Inoculate a single colony from a freshly streaked plate into 5 ml of LB medium containing the appropriate antibiotic for the plasmid and host strain. 2. Incubate with shaking at 200 rpm at 37℃ overnight. 3. 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.
