Iptg arabinose induction
WebSep 26, 2024 · There was a research to prove that induction with l-arabinose can serve as a substitution to combined induction with 1 mM IPTG . mlacI was placed under the P rhaBAD, which can strictly control the target gene and do not affect the growth of the strain, and rhamnose-inducible promoter had been widely used in the production of membrane … WebIsopropyl β-D-1-thiogalactopyranoside (IPTG, also known as lad-y) is a molecular biology reagent. This compound is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce E.coli protein expression where the gene is under the control of the lac operator.
