We have the proven scalable technology, end to end integrated platforms, knowledge and services to help you get your gene therapy to market. Work with us to increase your speed to commercialization or to improve process productivity and deliver therapies to transform lives.
Partner with us to accelerate and optimise your viral vector process
The journey to industrialization is exciting and can be challenging at times but development and optimisation obstacles can be overcome with support from Pall’s experts. Our Accelerator℠ process development services, specialize in designing, optimizing, and transferring scalable processes from pre‐clinical to cGMP commercial manufacturing, reducing time to market. Our team can draw on experience from multiple gene therapy viral vector projects to collaborate with you.
In 2019, Zolgensma®, an AAV-based viral vector gene therapy used in the treatment of spinal muscular atrophy was approved by the FDA and Pall’s iCELLis® fixed-bed bioreactor is used in the production. Zolgensma’s journey began at the Center for Gene Therapy at The Abigail Wexner Research Institute of Nationwide Children’s Hospital and eventually made its way to Novartis.
Together we can rapidly optimize your process, whether to prove readiness for industrial scale production or to increase capacity.
Cell Expansion and Virus Production
Efficient transfection and scalable cell culture are two of the upstream hurdles to overcome. Our solutions support you to design a robust, reproducible and scalable process for generating viral vectors.

The development of safe and effective viral vectors has accelerated the development of viral based therapies to treat a wide range of diseases. This has significantly increased the number of trials at all clinical stages as a growing number of approved therapies reach the market. This rapid rise has not been matched by the commonplace application of technologies that facilitate the industrialization of these viral vector production processes. Traditional technology, while seen to work well at a small scale, simply struggles to deliver the desired economic and practical solutions needed for large scale manufacturing.
As the industry quickly evolves, we offer technology that robustly scales from the laboratory and is proven to work in industrial processes to reduce your technology transfer risks. Whether you prefer an end to end, integrated platform to reduce development time or just one technology, we have the products, knowledge and services to help you deliver your gene therapy to market.
Your Process, Your Journey
Whatever direction your process choices take you in, our range of cell culture, purification and fluid handling technology supports scalable viral vector production such as adeno-associated virus (AAV) and lentivirus (LV).
Our keystone technologies can work on their own, or combine to create robust, but flexible integrated bioprocessing platforms that accommodate your unique processing requirements and accelerate your journey through process development to production.
These preconfigured platforms can also be provided in a prefabricated flexible POD® cleanroom from G-CON to further reduce the time required to arrive at a compliant manufacturing process.
Journey Guidance
Beyond our products, Pall Biotech has the knowledge and facilities to support and accelerate your process development. Together we can rapidly optimize your process and prove its readiness for industrial scale production and increase your speed to market.
For genetic disease therapy and for oncolytic virus therapy the scalability and flexibility of production at all scales is essential to quickly transition from process development to efficient, full scale manufacturing processes that are fully compliant with cGMP. This remains true for small and large scale gene therapies and for the creation of working seed stocks of purified virus as required for the ex-vivo cell modification that supports cell therapies such as CAR-T.
Our range of fixed bed and suspension culture technology overcomes these processing challenges to simplify your journey from laboratory to an industrial scale and from process development to regulated production. They combine with clarification, chromatographic purification, ultrafiltration and sterile filtration to deliver a total process solution and can be integrated with single-use fluid handling technology to create closed manufacturing systems that protect both product and operators during production.
