Optimization of an Anion Exchange Method for the Large-Scale Production of Plasmid DNA for Gene Therapy and DNA Vaccine Applications

This webcast features: Jenny England, Staff Scientist, Innovation & Applications, Thermo Fisher The advancement of gene therapy and plasmid DNA (pDNA) vaccines has highlighted the need for the development of a large-scale purification process to produce high purity plasmid DNA. Plasmid DNA serves as a foundation to produce viral vectors such as adenoassociated virus (AAV) or lentivirus (LV), a template for mRNA production during the in vitro transcription reaction and can be used directly as a pDNA vaccine. The typical…

Scaling-up AAV production? Take your time to develop best processes

The lack of standardization surrounding gene therapy production means process design can be more important than speed to clinic, says Oxford BioMedica’s CCO. The complexities of manufacturing monoclonal antibodies (mAbs) has been ironed out somewhat over the 30+ years of their presence commercially. But for the burgeoning gene therapy sector, there are no standardized mammalian-based platforms, for example, nor tried-and-tested upstream and downstream processes. “Viruses and viral vectors come in many shapes and sizes, each with their own characteristics,†Dave…
