Cryo-electron microscopy can provide high-resolution structural information about cells and organelles in the nearly native, frozen-hydrated state.

We demonstrate, by cryo-electron tomography of Escherichia coli cells, that a focused ion beam (FIB) can be used to thin whole frozen-hydrated cells in a convenient and essentially artifact-free way.
