Cryo-Electron Microscopy

Cryo-Electron Microscopy has revolutionized the field of high-resolution structural biology, and Dubochet, Frank and Henderson were awarded the Nobel Prize in Chemistry of 2017 due to their contributions for such an amazing development. Our laboratory was trained in EMBL-Heidelberg, where vitrification was invented by Jacques Dubochet. The Laboratory has high-end infrastructure of cryo-electron microscopes and associated sample preparation equipment.

The JEOL JEM-3200FSC

Our JEOL microscope is equipped with Gatan Digital Micrograph and currently, JADAS for automated image acquisition is being installed. In the near future, SerialEM will also become available at the microscope. We use it for high-end data acquisition of selected samples having been screened at the Glacios micrososcope.

Characteristics - JEOL JEM-3200FSC:
300 kV cryo-TEM
Field emission source
motorized apertures and intuitive control 
loading up to 3 samples simultaneously
K2 direct electron detector for high-end image acquisition
CCD camera for sample screening and alignments
in-column energy filter integrated into the electron optics
liquid He- or LN2- cooled side-entry goniometer 
The Thermofischer FEI Glacios

Our Glacios microscope is used for screening of samples under room-temperature and cryogenic conditions. We will be upgrading this machine with a phase plate, a direct electron detector, microED technology, and computational infrastructure.

Characteristics - Thermo FEI Glacios:
200 kV cryo-TEM
Field emission source
motorized apertures and intuitive control 
loading up to 12 samples simultaneously
minimal contamination rates
CMOS camera for sample screening and alignments
