Cryo-Electron Microscopy

Our goal is to reveal novel macromolecular interactions, up to the level of whole cells, by means of cryo-electron tomography and advanced pattern recognition algorithms. Cryo-electron tomography is the only technique that can obtain molecular resolution images of intact cells in a quasi-native environment.


FIB-SEM and Electron Tomography

In addition, we are using classical biological room temperature electron micoscopy. Ultrastructural preservation is assured in these preparations by prior high pressure freezing. We use this method to image larger volumina, as e.g. tissues and whole model organisms (currently C. elegans and Drosophila embryos) by focussed ion beam scanning electron microscopy and (after ultramicrotomy) by room temperature tomography.
