The “How” Behind Your “Why” in Gene Therapy Manufacturing
We believe in the power of process and partnerships in gene therapy manufacturing. Here’s a snapshot of our approach to your next success.
The Discipline to Drive Your Therapy Forward
It’s no big secret that companies with staying power have “a way,” a methodology so acutely honed — and so rigorously adhered to — that it drives certainty like nothing else can.
At Viralgen, we have “a way” for AAV gene therapy manufacturing that has both helped guide our clients to a 100% success rate in dossier submissions and is helping provide an ideal industry model for how to simultaneously increase production and lower costs.
Our Platform
Formed on the foundation of our processes, technologies, and digital bioreactor data, our platform delivers the predictability that could only come from running more than 1,500 batches of AAV. It’s how you can turn manufacturing into an independent variable for your project, minimizing process development timelines and risks while speeding your time to market.

Our Cell Line
Our proprietary Pro10™ cell line — derived from HEK293 cells and adapted for animal-derived component-free suspension culture — delivers high-yield production across all AAV serotypes and chimeric forms. And, in the process, it delivers highly efficient and scalable AAV manufacturing.

Our Triple-Plasmid Transfection Process
Our Pro10™ cell line is triple-transfected with the transfer plasmid containing your transgene, a helper plasmid providing adenovirus helper genes and a plasmid expressing AAV Rep and Cap genes — all included in our offer to position your transgene for success. It’s a combination primed to deliver robust scalability and functional advantages throughout production.
Our Purification Process
Our purification process ensures process residuals are minimized and full capsids are prioritized with a scalable, agnostic approach. We manage 80% of testing – including NGS – in house, ensuring your product both moves through its journey efficiently and maintains the identity, integrity, and purity required to help get it patient-ready.



How Our Team Positions Yours for Success
Our passion for your success will come through clearly in our first meeting (and in every one after that, for that matter).
