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.

WebNov 14, 2024 · Three factors, which included temperature after induction, time after induction and IPTG concentration, with three levels each, were considered, accounting for 15 sets of experiments. WebFeb 13, 2024 · Indeed, biomass production gradually rose when induction was made at the higher OD600. When induction was made in the early exponential growth phase, bacterial metabolic resources were channeled to produce recombinant protein comprising up to 50% of the total cellular protein [37, 38]. Based on this reasoning, low cellular growth rate …
