Downstream Process Development For Vaccine Manufacturing

Downstream Process Development For Vaccine Manufacturing


The purification of vaccines and gene therapy/viral vector products is a key part of a drug manufacturing process that requires high levels of product purity and process reproducibility. Pall has a range of technologies and offers field-based support and lab-based process development services that enable end users to purify and recover their high-value products. The process strategies to improve purity and yield as well as the challenges associated the purification of viral vector process will be discussed.


Jon Petrone


Senior Director, Process Development Services and Scientific Laboratories Services Consultancy Teams supporting Purification, Viral Vector and Gene Therapy Technologies


Jon leads Pall Biotech’s Process Development Services (PDS) and SLS consultancy teams supporting purification, viral vectors, and gene therapy technologies. The PDS team provides upstream, downstream, and analytics process development, scale-up, and tech transfer services to support emerging therapeutics such as gene/cell therapies (and proteins) as well as supporting new manufacturing methods such as continuous bioprocessing. 


The SLS consultancy teams provides field-based customer and technical support that utilizes Pall’s technologies and products to create process solutions for the production and purification of biopharmaceutical products, such as viral vectors, monoclonal antibodies and gene therapy products. 


He has over 35 years of experience supporting downstream purification applications from cell harvest through final bulk fill. Prior to joining Pall 15 years ago, Jon was responsible for the process development and clinical/commercial support of the membrane based separations and centrifugation steps at Wyeth BioPharma. Previously, he held various applications/product development and system sales roles at Millipore.

Getting Ready for SUT X-Ray Irradiation

Biotech Research & Commercialization Solutions | Pall Corporation webinar series

Why the introduction of X-ray sterilization technology is a critical change for single-use industry, and how gamma and X-ray irradiation compare


The market demand for gamma irradiation, the current primary method for the sterilization in SUT, will soon significantly exceed supply, creating an urgent need for alternatives.


Join Christelle Marcoux from GSK Vaccines (BioPhorum workstream member on alternatives to gamma sterilization) and James Hathcock, PhD of Pall Corporation (Bio-Process Systems Alliance X-Ray Committee Co-Chair) as they discuss the introduction of X-ray sterilization technology.


You will learn more about:


  • Why this is a critical change for industry and the responsibilities of each stakeholder
  • Key questions to address for biomanufacturers
  • How gamma and X-ray irradiation compare
  • What testing has been completed and key milestones for readiness for industry
  • An example of how to qualify a SUS sterilized with X-ray irradiation
