About

ExpreS2ion Biotechnologies is a world leading CRO biotech company

Our company has a proprietary and complete S2 recombinant protein technology base – ExpreS2, which was developed over ten years at Pharmexa A/S. We have in-depth practical experience with the non-viral Drosophila S2 expression technology for the production of recombinant proteins for preclinical development and for use in clinical trials.

Contribution to Malaria Vaccines/Research

By leveraging our ability to express malaria parasite proteins with ExpreS2 a cGMP-compatible system, we have enabled progress of malaria vaccine candidates into clinical research. ExpreS2ion Biotechnologies is working with top academic teams to advance vaccines directed at different malaria stages of infection: blood stage malaria and pregnancy malaria.

“Challenging proteins made easy”

The ExpreS2 system, based on Drosophila S2 cell expression can solve your “protein dead-ends” by providing an alternative, cGMP-compatible expression system.
When to choose the S2 expression system:

  • Secreted or secretable proteins
  • Low/non-expressing proteins in HEK293 or BEVS
  • Issues with protein cleavage during production
  • Heterodimers or further multimeric proteins
  • If variable glycosylation is an issue
  • If you need a cGMP-compatible system

ExpreS2ion Biotechnologies specializes in establishment of high-producing cell lines together with upstream process development and working with customers to solve technical problems in molecular biology, protein expression or other issues relating to S2 cells. S2 related reagents are also available.
