Why GTP?

Our track record

Our experience spans process development as well as hundreds of challenging recombinant proteins. We are well placed to recommend the most suitable and least risky strategy for your programme.

GTP has a rich experience in the design of bioprocesses for a diversity of proteins and applications


With a vivid scientific interest in all - even “non-conventional” - protein projects, GTP has acquired vast experience producing a diversity of proteins: antibodies, antibody fragments, enzymes, cytokines, growth factors, hormones, receptors, transcription factors…

We know that no single expression system is ideal for each and every protein and project, so we have always worked with a diversity of them. Our experience covers all prominent industrial microbial, mammalian and insect cell expression systems such as E. coli, L. lactis, P. pastoris, CHO, HEK and Sf9.

Over the past 15 years, 150+ biopharmaceutical, diagnostic, agrichemical and other life science companies have entrusted us with a variety of recombinant projects:

For the projects ultimately requiring production at a cGMP manufacturing site, our track-record for successful handovers to a diversity of CMO companies proves that our processes can be successfully transferred.
