Protein kooekspressed during iptg induction
WebbIPTG 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. http://wolfson.huji.ac.il/expression/procedures/bacterial/glucose%20supression.pdf

WebbThere are two common protocols to induce proteins by IPTG: fast induction and slow induction. For fast induction, you can harvest your protein of interest at least 3-4 hours after IPTG induction. Whereas, for slow induction, you can get your protein at least 12-16 hours post IPTG induction.
