Electron Microscope Tomography and Single-particle Reconstruction

Electron Microscope Tomography and Single-particle Reconstruction

Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Cryo-electron Microscopy

Cryo-electron Microscopy

Conventional electron microscopy (EM) involves dehydration, fixation, and staining of biological samples, which distorts the native state of biological molecules and results in several artifacts. Also, the high-energy electron beam damages the sample and makes it difficult to obtain high-resolution images. These issues can be addressed using cryo-EM, which uses frozen samples and gentler electron beams. The technique was developed by Jacques Dubochet, Joachim Frank, and Richard Henderson, for...

To discuss recent advancements in cryo-ET and correlative approaches for high-resolution cellular visualization.

Main Methods:

Cryo-electron tomography (cryo-ET) for 3D reconstruction of cellular architecture (2-6 nm resolution).
Correlative light microscopy combined with cryo-ET for medium-resolution insights.
Integration of high-resolution structural methods (e.g., X-ray crystallography) with cryo-ET data.

Main Results:

Cryo-ET provides detailed 3D reconstructions of near-native cellular structures.
Correlative approaches offer insights into cellular processes at different resolutions.
Integration of structural data with cryo-ET enhances understanding of macromolecular assemblies.
