Recombinant adeno-associated virus (rAAV) is one of the most used viral vectors for gene therapy. However, large-scale rAAV production is labor intensive and costly due to the requirement for an efficient rAAV synthesis in stable cell lines. A team of researchers at Nationwide Children’s have developed a simple and cost-effective technique to ease the production of rAAV. Compared to existing methods, this approach allows more rAAV genomes to be encapsulated into infectious rAAV particles while allowing the production of rAAV in several cell types. The materials and methods of this invention are covered in the US issued patent 8,409,842.
