Pioneering high-yield cell suspension line

Long before many AAV manufacturers existed, we recognized a universal need that crosses all AAV therapeutics – the need for a process that increases production and lowers cost. In 2010, we introduced Pro10™, a best-in-class cell line for generating novel AAV therapeutics. Our system uses a human embryonic kidney (HEK)-based cell line in serum-free suspension media to develop and produce AAV vectors at scales and yields that are the highest in the industry.

Pro10 process: Clone sequence into plasmid, large scale plasmid production + Transgene + Ad Genes + Rep/Cap = AAV
Pro10 process: Clone sequence into plasmid, large scale plasmid production + Transgene + Ad Genes + Rep/Cap = AAV

Pro10™ was the first HEK293 based suspension cell line to achieve high-yield AAV manufacturing without using any human or animal derived by-products to grow in bioreactors. This results in faster, safer, and highly scalable AAV vector manufacturing that sets new standards for the industry.

Pro10™ is used in AskBio’s Viralgen manufacturing facilities and is licensed by leading global biopharma companies.

  • Produces the highest yields of AAV vectors in the industry
  • Universal manufacturing system that produces all serotypes and chimeric capsids packaging single-stranded and self-complementary genomes
  • Significant cost advantages with transient transfection of a patent-protected cell line  
  • Scalable production from benchtop to bioreactor allowing for early assessment of vectors enabling rapid scale-up
  • Flexible production platform that allows early feasibility benchmarks to be translated to clinical development
