Transmission Electron Microscopy01:15

Transmission Electron Microscopy

7.7K
In 1931, physicist Ernst Ruska—building on the idea that magnetic fields can direct an electron beam just as lenses can direct a beam of light in an optical microscope—developed the first prototype of the electron microscope. This development led to the development of the field of electron microscopy. In the transmission electron microscope (TEM), electrons are produced by a hot tungsten element and accelerated by a potential difference in an electron gun, which gives them up to 400...

Overview of Electron Microscopy

The wavelengths of visible light ultimately limit the maximum theoretical resolution of images created by light microscopes. Most light microscopes can only magnify 1000X, and a few can magnify up to 1500X. Electrons, like electromagnetic radiation, can behave like waves, but with wavelengths of 0.005 nm, they produce significantly greater resolution up to 0.05 nm as compared to 500 nm for visible light. An electron microscope (EM) can create a sharp image that is magnified up to 2,000,000X.

Preparation of Samples for Electron Microscopy01:20

Preparation of Samples for Electron Microscopy

7.7K
To be visualized by an electron microscope, either transmission or scanning, biological samples need to be fixed (stabilized) so the electron beam does not destroy them and dried thoroughly (desiccated/dehydrated) so the vacuum does not affect them. Fixation needs to be done as quickly as possible because the sample properties will start changing as soon as it is removed from its natural environment. For example, in a tissue sample, the oxygen levels begin decreasing, causing an altered...

Cryo-electron Microscopy01:28

Cryo-electron Microscopy

4.5K
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 preserve cellular integrity during sample processing for electron microscopy.

Main Methods:

  • Development of a new protocol using conventional reagents and equipment.
  • Application of the protocol to cell cultures prior to electron microscope observation.

Main Results:

  • The developed protocol successfully reduced cell compression to none or minimal deformation.
  • Preservation of cellular structures was achieved during centrifugation.

Conclusions:

  • The new protocol effectively mitigates the adverse effects of centrifugation on cell structures.
  • This method offers a viable solution for high-fidelity electron microscopy sample preparation.
