GMP Protein Production

GMP Protein Production Highlights

  • Bacterial / mammalian hosts
  • Multiple bioreactors and multi-tray formats
  • Cell harvest by centrifuge or filtration
  • Protein refolding
  • Scalable downstream processing

Waisman offers superior quality recombinant protein process development and manufacturing services. Our strength lies in the ability to develop a customized process that is reproducible and fully scalable, yielding an end product that meets industry standards for FDA submission. All recombinant protein production campaigns are performed in either our Microbial Cell Suites or Mammalian Suites.
