Enhancing Plasmid DNA (pDNA) Production: Innovations in Process, Manufacturing, and Purification Techniques
A plasmid DNA production process was performed comparing conventional Erlenmeyer flasks with LB medium and the Thomson’s Ultra Yield® system. E. coli cells were cultivated in both systems in the INFORS HT Multitron incubator shaker, bacterial growth was monitored, and the plasmids were purified at the end of cultivation. Subsequently, the quality of the isolated plasmids was analyzed by HPLC.
The combination of the Ultra Yield® flasks with the enriched Plasmid+® medium and the AirOtop® enhanced seal led to higher cell densities and a 21-fold higher amount of plasmid than in Erlenmeyer shake flasks with LB medium.
