Cell-free expression using Phenomics™ technology
Protéus invented and patented Phenomics™, a powerful cell-free technology for expressing functional proteins. Cell-free expression has been developed to overcome the limits of cell-based expression, permiting to obtain labeled proteins (with radio-isotopes or heavy-isotopes), difficult-to-express proteins (e.g cytotoxic proteins) or rapid protein expression as required in high-throughput screening assays.
Our Phenomics™ platform includes several cell-free systems, prokaryotic (E.coli, Bacillus, Pseudomonas) and eukaryotic (Trichoderma). We have developed specific vectors for each system and proprietary PheMix™ translation reagents.
At Protéus, we want cell-free expression to be a user-friendly technology. Therefore, Phenomics™ does not require any dedicated instrument or consumable. Additionally, we have reached such a high level of optimisation of the technology that Phenomics™ can now be implemented using a straightforward one-pot protocol, hence dramatically simplifying the use of the technology for both prokaryotic and eukaryotic Phenomics™ systems.
Benefits of Phenomics™
- Rapid expression of genes and gene fragments
- Express difficult-to-express proteins (toxic to cell-based systems or non-natural proteins)
- Labeling of proteins (heavy-istopes and radio-isotopes)
- Suitable for high-throughput screening assays
