Pioneering C3P3 tools for bioproduction


The expression yields or titers of recombinant proteins and viruses by the standard expression systems remain a major hurdle in the biologics R&D and production pipeline. Based on its C3P3 technology, Eukarÿs develops fundamentally new tools to boost the bioproduction performances in mammalian cells.



The bioproduction tools developed by Eukarÿs consist of mammalian cell lines that stably express the C3P3 enzyme only (CHO-K1 cells) or together with specific plasmids optimized (HEK-293 or BHK-21 cells).

These artificial expression systems are suitable for production of high yields of recombinant proteins or recombinant viruses, respectively.


The Pros of C3P3 expression system:

  1. Reduce timelines and accelerate decision-making: C3P3 bioproduction tools are immediately available with minimal optimization efforts
  2. Increase performances: ~5 fold greater yields of recombinant proteins by transient transfection – up to 100-fold greater titers of recombinant RNA orthoreoviruses in comparison to existing technologies
  3. Reduce the costs of bioproduction: reduced bioproduction capacities, cell culture volume and amounts of reagents
  4. Ensure consistent product quality: C3P3 does not alter cell translation and has no impact on downstream translation process
Our business model

Off-the-shelf C3P3 bioproduction tools can be used for other laboratories under license grants
