Structural Biology

Pioneer in structural biology services

In-house cryo-EM and more than 7000 X-Ray structures solved 

Proteros heritage lies in Protein X-Ray structures. Based on a 30 years academic history, rewarded by a Nobel Prize of Prof. Dr. Dr. Robert Huber related to protein crystallography, Proteros became one of the first service provider focusing on structural biology (please refer to "our history").

We represent a very large and well experienced X-Ray crystallography service group, covering more than 25 structural biologist, including 4 cro-EM experts, all  with a strong academic pedigree, numerous per reviewed publications and have solved more than 7000 structures.

Our technology platform includes co-ownership of a synchrotron beamline  at the well-known Swiss Light Source and proprietray technologies (Free Mounting System) for crystal optimization. 

Proteros Premium Structural Services

We offer premium X-Ray and cryo-EM services covering:

  • the RIGHT protein science and construct design
  • crystallization, data collection, structure determination
  • Access to X-ray including synchrotron and in-house cryo-EM
We have an in-depth experience of successfully working with a wide range of drug targets, including:
  • membrane proteins / epigenetic complexes
  • protein complexes / protein-DNA/RNA complexes
  • protein/lipid kinases / proteases
  • biologics (Fab-Antigen structures).

Cryo-EM Structures

We have already industrialized Protein X-Ray Crystallography - now we are industrializing Protein cryo-EM !

Proteros cryo-EM Service includes:
  • Protein preparation for cryo-EM
  • EM-feasibility analysis
  • cryo-EM condition optimization
  • Low/High resolution cryo-EM structure analysis
In a project you can enter and leave the cryo-EM process at nearly any stage depending on your project requirements, but we recommend our complete cryo-EM service.
 
With direct and instant access to protein science, grid preparation, condition optimisation and the latest high-resolution cryo-electron microscopes you can be sure to REACH RIGHT FASTER for your downstream application.
