The Electron Microscopy Data Bank (EMDB) is a public repository for cryogenic-sample Electron Microscopy (cryoEM) volumes and representative tomograms of macromolecular complexes and subcellular structures. It covers a variety of techniques, including single-particle analysis, helical reconstruction, electron tomography, subtomogram averaging, and electron crystallography. More...

A total of 2,540 respondants took the time to fill in this EMBL-EBI survey. We will learn how EMDB and other services like EMPIAR and PDB help you and this will help EMBL-EBI make the case for why open data resources are critical to life science research. Thank you for the incredible number of responses.
