Cryo-electron Microscopy01:28

Cryo-electron Microscopy

3.2K
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...

Electron Microscope Tomography and Single-particle Reconstruction

2.3K
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...

Area of Science:

  • Virology
  • Cell Biology
  • Microscopy

Background:

  • Viral replication depends on host cells and involves dynamic intracellular stages.
  • Studying these dynamic viral processes in situ is challenging due to their transient nature and overlap with cellular activities.

Purpose of the Study:

  • To introduce correlative three-dimensional (3D) imaging methods for studying viral morphogenesis.
  • To enable in situ characterization of intracellular stages of the viral life cycle under near-native conditions.

Main Methods:

  • Correlative microscopy integrates visible light microscopy with high-resolution imaging techniques.
  • This approach allows for labeling, localization, and functional characterization alongside structural insights.

Main Results:

  • Correlative imaging provides a comprehensive view of subcellular events within the cellular context.
  • It facilitates the exploration of viral morphogenesis and other intracellular viral cycle stages.

Conclusions:

  • Correlative 3D imaging is essential for understanding viral morphogenesis and intracellular viral dynamics.
  • Integrating whole-cell imaging with high-resolution structural biology is key to deciphering viral progeny production and dissemination mechanisms.
