The Cryo-Electron Microscopy Platform is hosted at the ALBA Synchrotron as part of the JEMCA ( Joint Electron Microscopy Center at ALBA) and operated by the IBMB-CSIC.

The Platform (EM01-Cryo-TEM ) is equipped with:

A 200 kV TEM, Glacios from ThermoFisher Scientific,

with extreme field emission gun (X-FEG) optics, equipped with a cryogenic sample manipulator robot for up to 12 grids and a last generation Falcon 4 direct electron detector with a capability of 300 movies/h. Its high level of automation and user guidance of experimental settings enable scientists to efficiently unravel protein structures in 3D, as well as understand their functional context in the biological cell.

There is a sample preparation room equipped with the following equipment:

  • Vitrobot Marc IV vitrification system
  • GLoQube to grid treatment previous to vitrification
  • Equipment to clip the grids
  • L-N2 dewars to store the grids

The data sets generated are pre-processed on-the-fly with a powerful GPU workstation and can be stored up to 30 days at ALBA. Users can download their data either locally using an external disk or through the network.

This microscope has been funded through ERDF and owned by six partner institutions (the IBMB-CSIC, acting as owner of the equipment, the ALBA Synchrotron, the Spanish National Research Council (CSIC), the Institute for Biomedical Research (IRB Barcelona), the Centre for Genomic Regulation (CRG), and the Universitat Autònoma de Barcelona (UAB))

This project is co-financed by the European Regional Development Fund of the European Union in the framework of the Operational Program ERDF of Catalonia 2014-2020 with a grant of 850,000.00 €
