Iptg protein induction
WebUsing a gfp reporter strain we compared TMG and IPTG induction at single cell level and showed that bimodal induction with IPTG occurred at approximately ten-fold lower concentrations than with TMG. Furthermore, we observed that lac operon induction is influenced by the transacetylase, LacA. WebMay 20, 2015 · The IPTG-based auto-induction was also reproduced in shaking flasks. Therefore, IPTG can be used in auto-induction media for protein expression in batch-cultured . Furthermore, we show that acetate or arabinose can have significant effects on the auto-induction mechanism. Citing Literature Volume15, Issue8 November 2015

WebIPTG is often used in the induction of recombinant proteins, is a substrate for thigalactoside transacetylase and has been reported to induce penicillinase in bacteria. IPTG is commonly used in cloning procedures that require induction of β-galactosidase and is most often used with X-Gal for blue/white acterial colony screening. WebIPTG is commonly used in cloning procedures that require induction of β-galactosidase and is most often used with X-Gal (Gold Bio #X4281C) or Bluo-Gal (Gold Bio #B-673) for blue/white colony screening or Magenta-Gal (Gold Bio #B-378) for red/white colony screening of bacterial colonies. IPTG is also used in the induction of recombinant proteins.
