Structural Biology
Pioneer in structural biology services
In-house cryo-EM and more than 7,000 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 biologists, including 4 cryo-EM experts, all with a strong academic pedigree, numerous peer reviewed publications and have solved more than 7,000 structures.
Our technology platform includes co-ownership of a synchrotron beamline at the well-known Swiss Light Source and proprietary technologies (Free Mounting System) for crystal optimization.
