Electron cryo-tomography and subtomogram averaging enable visualization of protein complexes in situ, in three dimensions, in a near-native frozen-hydrated state to nanometer resolutions. To achieve this, intact cells are vitrified and imaged over a range of tilts within an electron microscope. These images can subsequently be reconstructed into a three-dimensional volume representation of the sample cell. Because complexes are visualized in situ, crucial insights into their mechanism, assembly process, and dynamic interactions with other proteins become possible. To illustrate the electron cryo-tomography workflow for visualizing protein complexes in situ, we describe our workflow of preparing samples, imaging, and image processing using Leginon for data collection, IMOD for image reconstruction, and PEET for subtomogram averaging.
