Escherichia coli

For the expression of a recombinant protein in a bacterial system, ARTES provides a highly efficient E. coli platform. The platform is characterized with a host/vector toolbox for optimal expression and with the ability to release recombinant proteins into the culture supernatant.

Because of the releasing feature, the identification and purification of the recombinant protein after fermentation is much easier than in a normal E. coli fermentation process. After fermentation, the protein will be found in the supernatant of the broth. For the purification process, steps as cell disruption or folding and refolding will not be necessary any more. The secretion property of our E. coli system flows directly into the efficiency of production costs for the manufacturing of the recombinant product of our client.

Hansenula polymorpha



ARTES uses one of the most important industrial expression systems, the methylotrophic yeast Hansenula polymorpha (syn. Pichia angusta). For our platform technology, we have all relevant IP rights as well as unpatent know-how. Our expertise is on trouble-shooting and project management. ARTES ensures 100% freedom-to-operate for all clients and licensees and guarantees a smooth and high standard project progress.
