Iptg induces tac production

WebWe developed a system in which IPTG as inducer was replaced by lactose which induces the tac-promoter with the same efficiency. In E. coli CW3011 (pOF1.0) lactose is utilized as inducer and carbon source even in the presence of glucose, presumably as a consequence of the overproduction of lac-permease. WebSpecifically, the influence of IPTG (isopropyl-beta-D-thiogalactoside) concentration, …

WebMay 27, 2016 · After 3 h cultivation, IPTG was added to medium to induce tac promoter. Unlike K. pneumoniae (pTAC- puuC ), K. pneumoniae (pLAC- puuC ) does not need any inducer for PuuC expression because lac is ... WebWhen the OD600 reaches between 0.6-1.0 (approximately 2 hours), add IPTG to a final concentration of 500µM. This will induce the expression of the His6-GFP protein. Allow the culture to grow and express the GFP by shaking at 37°C for 16-24 hours. Note that in some cases, lowering the temperature after the induction may help proteins fold.

WebT7 expression is often very robust but may suffer from undesirable basal (non-induced) transcription especially in DE3 strains. Regulation of IPTG-induced T7 expression is accomplished by co-expressing the lac repressor from a plasmid or a host-encoded lacI gene and by co-expressing T7 lysozyme, the natural inhibitor of T7 RNA polymerase activity.
