Z05 - Three-dimensional cryo-electron microscopy

Prinzipal Investigator

Prof. Dr. Christian Spahn, Charité Berlin

The overall aim of project Z05 is to facilitate 3D cryo-electron microscopy (3D cryo-EM) analyses of membrane scaffolding. In close collaboration with the projects of the SFB958, they will foster molecular cryo-EM to determine the structure of isolated macromolecular assemblies by the single particle approach or by molecular cryo-electron tomography (cryo-ET) in combination with sub-tomogram averaging. Furthermore, they will newly implement the workflow for cellular cryo-ET for visualizing membrane scaffolds in the native environment of the cell.
