High-yield plasmid dna production
WebPlasmid DNA Manufacturing Services As a critical starting material in the production of many advanced therapies including viral vectors and RNA vaccines, cell and gene therapy research at any scale requires plasmid DNA manufacturing. Our specialists provide custom plasmid production that fits your project specifications. WebThis chapter describes a simple fed-batch fermentation process for producing bacterial cell paste enriched with high-quality plasmid DNA. A constant feeding strategy results in a medium cell density culture with continuously increasing plasmid amplification towards the end of the process.
