Contract manufacturing services for recombinant proteins


Novasep is a trustable and agile partner to drive your project to success. Over the years we have manufactured a large number of recombinant proteins using various expression platforms.Novasep CMO Fermentor

Expert in cell-culture and fermentation processes, we can produce your:

  • Antigens from virus, bacteria or parasites
  • Fusion proteins and conjugated proteins
  • Enzymes and other metabolites (IFN, IL-10, etc.)


Unique capabilities and methodology

We offer the following range of services:

  • Full process and technological transfer
  • Upstream process development:
    • Cell adaptation to serum-free, suspension growth
    • Creation of Master Cell Bank (MCB) and Working Cell Bank (WCB)
    • Optimization of cell culture and fermentation parameters (feeding strategy…)
    • Conditions of expression induction optimization
    • Lysis conditions optimization
  • Downstream process development
    • Clarification optimization
    • Optimization of purification steps (filtration and chromatography operations)
    • Virus inactivation conditions
  • Process scale-up and validation
  • Aseptic F&F for liquids in glass vials
  • Full analytical transfer, development and qualification

Our track record

We have a rich and extensive experience in the cGMP production and purification of multiple recombinant or native proteins including:

  • Large panel of viral proteins from HPV, VZV, CMV, EBV, HSV, etc.
  • Parasites proteins (for example from Plasmodium, responsible of malaria)
  • Lipo-polysccharides from V.cholerae, N.meningitidis, etc.
  • Conjugated proteins with polysaccharides and fusion proteins
  • Monoclonal antibodies and mAb fragments
  • Enzymes
  • Hormones/cytokines & growth factors including IFN, IL-10, hTFF1, etc.

Our BSL2/BSL3 pathogens manufacturing facility, dedicated to contained production, can be proposed to manufacture hazardous biologics or compounds such as toxins and allergens. Learn more about our BSL3 pathogens manufacturing capabilities.
