Assessing the potential -
VTU´s streamlined feasibility studies

Straightforward determination of expression potential & rapid production of protein samples

You instantly need a few mgs of recombinant protein?

Expression in other systems is troublesome or failed?

Expression in commercially available yeasts was not satisfying?

Are you searching for a powerful expression system suitable for industrial protein production?

In a lean feasibility study we will elucidate the expression potential of your recombinant protein in minimum time. Starting from an optimized synthetic gene sequence, results will be available within 3 to 4 weeks including cloning, transformation and screening giving you an immediate answer for a reliable go/no-go decision. Positive candidates from micro-scale screening can be directly transferred to bioreactor cultivation enabling both the production of initial protein samples as well as further assessment of the potential for improvement.

After positive assessment we provide yield optimization by applying
VTU´s comprehensive production strain development.
