Cryo-EM-GLACIOS

The Thermo Fisher Scientific Glacios is a 200 kV transmission electron microscope with X-FEG and Falcon 4i detector coupled to a Selectris X energy filter for high-resolution structure determination of biological (and other soft matters) macromolecules. Its 12-grid autoloader allows efficient loading and unloading of cryo-EM grids. The automated EPU and Tomo software systems are used for automated data collection, capable of producing >300 movies/hour, for high-resolution single particle analysis and cryo-electron tomography.
