Waisman Biomanufacturing

Clinical Production

GMP Plasmid DNA

Waisman's platform plasmid manufacturing process yields up to multi-gram quantities of clinical, CGMP grade plasmid DNA that can be used for direct injection or ex-vivo/further manufacturing applications. Waisman has delivered plasmid DNA vaccines up to Phase 2 clinical trials and can support Phase 3/commercial for plasmid DNA used as an ancillary material. 

Plasmid Production Specifics

  • Clone optimization and Master/Working Cell bank production and testing
  • CGMP production of multi-gram batches for direct injection and ancillary use
  • 30-120L steam-in-place fermentor capacity
  • Scalable manufacturing process free of organic solvents and animal derived products
  • Quality Control testing including HPLC and qPCR
  • In-house development of custom potency assays

GMP Plasmid Highlights

  • High yield fermentation
  • No animal derived enzymes or organic solvents
  • Scalable production process
  • Milligram to multi-gram capacity
  • DNA vaccines, ex vivo or bioprocess manufacturing applications
