2018 Cryo-EM School

The Fall 2018 Cryo-EM School took place at the Netherlands Centre for Electron Nanoscopy (NeCEN). From the 22nd of October until the 16th of November, 6 participants received hands-on Titan Krios training from the experienced NeCEN EM scientists and Thermo Fisher applications support team. 

Part of the Cryo-EM School was a 3-day Image Processing Course organised in collaboration with the Biocomputing Unit of the Spanish National Center for Biotechnology (CNB).


NeCEN, Leiden University, The Netherlands


  • Thermo Fisher Scientific
  • The Netherlands Centre for Electron Nanoscopy (NeCEN)
  • The Biocomputing Unit of the Spanish National Center for Biotechnology (CNB)


The curriculum is divided in two parts.

  1. Online lectures about the theory of cryo-EM single particle analysis as well as practical demonstrations by Grant Jensen (CalTech) and Matthijn Vos (Thermo Fisher Scientific) (http://em-learning.com). The school participants have to follow the online course and take the self-evaluation test before coming to NeCEN for practical hands-on training.
  2. Hands-on practicals on the different aspects taught online.
  • Cryo-EM sample freezing on a vitrobot
  • Cryo-EM grids clipping and loading for autoloader systems
  • Cryo-EM sample screening
  • Titan Krios alignments
  • Automated Single Particle Data Acquisition with EPU
  • Basics of image processing within Scipion Environment in the cloud
