Range of Services

We offer a complete range of milestones-based research and production services including:
• Standard protocol reproduction
• Feasibility studies (mono- or multi-expression systems)
• Development of fermentation protocols and scaled-up protein production
• Refolding studies for proteins expressed in inclusion bodies
• Fast protein expression for microarray applications
• Fully integrated research contracts

All projects submitted by our clients will go through a thorough scientific evaluation before we issue a customized development program and quotation.

Sample Research Contract

Duration: 6-8 months

Resources: 4 FTEs + senior Project Director

Platforms: Molecular biology, cell culture and bacterial expression

Objectives: Production of 20 vaccine/antigen candidates for Proof of Concept
- Design of constructs (80)
- Expression tests to determine relevant system
(bacterial vs mammalian)
- Evaluation and categorization of candidates (difficult-to-express proteins, solubility profile)
- Development of custom expression and purification protocols for each candidate
- Small scale production and full characterization of batches (20mg, >90% purity) to be injected in animals
- Supply of all documentation / certificate of analysis + QA support
