Protein production services
Protéus Bioproduction Expertise
Protéus has a solid experience of industrial protein production, acquired through its exclusive partnerships with
leading industrial partners. We have successfully expressed a wide variety of proteins, demonstrating our know-how in the development of
competitive bioprocesses, as well as our
compliance with stringent quality standards and regulations.
Our track record includes the production of biocatalysts used for the synthesis of active pharmaceutical ingredients (APIs) and candidate therapeutic proteins for preclinical investigations.
This expertise is now available through PSI for
producing the protein you need, with the quality you need.
PSI Prod'line™ bioproduction services allow production of:
- Microbial biomass (up to 300L scale)
- Pilot scale batches for preclinical and pre-industrial development
- Non-therapeutic batches (e.g. biocatalysts)
Accelerate timelines and meet your goals
The goal of our experienced team of process development scientists is to establish
cost-effective, robust and scaleable biologic manufacturing solutions for your projects. We focus on development strategies that maximise expression and yield while meeting your product specifications.
Dedicated project leaders ensure smooth operations and create a strong synergy between the different skills. They coordinate each of your projects to achieve quality and on-time delivery.

Capacity
Protéus routinely operates 30L fermentors, allowing to quickly start preclinical and pre-industrial evaluation. Larger volumes can be processed upon request and processes can be developed to scale up to cubic meter scales.
Quality
Our bioprocess unit is operated using GMP-grade equipments and procedures. We maintain
stringent quality control policy to address our clients’ requirement for traceability and safety.
