  • Title: High Yield of Recombinant Protein in Shaken E. coli Cultures with Enzymatic Glucose Release Medium EnPresso B.
    Author: Ukkonen K, Neubauer A, Pereira VJ, Vasala A.
    Journal: Methods Mol Biol; 2017; 1586():127-137. PubMed ID: 28470602.
    Abstract:
    Expression of recombinant proteins in sufficient quantities is essential for protein structure-function studies. The most commonly used method for recombinant protein production is overexpression in E. coli cultures. However, producing high yields of functional proteins in E. coli can be a challenge in conventional shaken cultures. This is often due to nonoptimal growth conditions, which result in low cell yields and insoluble or incorrectly folded target protein. To overcome the shortcomings of shake flask cultivation, we present a cultivation method based on enzymatic glucose delivery. This system mimics the fed-batch principle used in bioreactor cultivations and provides high yields of biomass and recombinant proteins in shaken cultivations.
