Expression systems

We will assist you in choosing the most appropriate expression system according to your protein and the final objective of your project.

We work with a variety of expression systems to best meet your needs

Drawing on our  multi-system capability, we offer a science-based decision for system selection.

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. coliP. pastoris, CHOHEK and Sf9.

This combined experience of hundreds of challenging recombinant proteins and multiple expression systems is a great asset to advise on the most suitable and least risky strategy for your programme.
