ExpreS2ion Biotechnologies is a world leading CRO specialising in developing cell lines and processes based on Drosophila S2 cells. Our company has a proprietary and complete S2 recombinant protein expression platform: ExpreS2, which was developed over ten years at Pharmexa A/S.

ExpreS2 is a uniquely successful tool for non-viral, insect cell-based expression, and we are the only service company with in-depth practical experience in its use – both in preclinical development and in clinical trials.

The ExpreS2 platform is excellent in all phases of drug discovery, R&D and manufacturing as it offers fast access to protein and easy establishment of stable polyclonal pools. This results in high protein expression levels.
