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...
