WebNational Center for Biotechnology Information WebIt inhibits the lac promoter that transcribes T7 RNA polymerase which binds to the T7 promoter of the plasmid to initiate transcription of the dLDH gene. The lac repressor binds to both promoters and are induced by the same ligand: IPTG. Since both repressors are affected by IPTG, this controls the expression of the dLDH gene.

WebIPTG at a final concentration of 1 mM. In the case of E. coli BL21(DE3), the optimal IPTG concen-tration in LB (0.1 mM, 0.5 mM, 1 mM or 1.5 mM), need for IPTG in M9 medium (0 mM) and optimal OD 600 (0.4–0.9) for induction of protein expression were also evaluated. Afterwards, other culture media (§2.2.1) and other combinations of media were ... WebIn contrast, increasing IPTG concentration caused a decrease in overall RFP expression. This decrease in RFP expression was most likely due to plateauing bacterial growth. Figure 2. OD600 kinetic trace. OD600 readings were recorded every 10 minutes over the course of 24 hours (n=3). As IPTG concentration increased, bacterial growth rate decreased.
