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 … WebIPTG concentration for induction is around 0.5-1 mM. How do I make IPTG 0.1 M concentration solution in 50 mL?
