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™. In 2017, we were listed on NASDAQ First North Stockholm [ticker: EXPRS2].

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 – we have evidenced 10-100 times higher yields than for example baculovirus or HEK293. ExpreS2™ is regulatory approved for performing clinical investigations in Europe, USA, and Africa.

That’s why when you work with us, you experience a group of highly engaged collaborators, eager to take on your protein challenge as our own. We work to quickly, efficiently and cost-effectively provide the proteins you need, with the right quality, when you need them.
