rAAVs, host-cell contamination and ddPCR
In this episode of Talking Techniques, supported by Bio-Rad, we discuss a key component of many gene therapies: recombinant adeno-associated viruses (rAAVs) and their production. These viruses act as efficient, accurate delivery vesicles for the gene therapy’s plasmid.Speaking to Associate Director of Biopharma Product Marketing at Bio-Rad Laboratories, Mark White, we take a look at the different expression systems used for their production and compare their advantages, before looking at some of the challenges involved in the production rAAVs, such as host-cell contamination.Discover the tools that can help minimize host-cell contamination and differentiate between nuclease resistant and nuclease reactive contaminant DNA and find out about some of the most exciting developments in rAAV technologies.
