Insights

A new, shorter fixation protocol for transmission electron microscopy (TEM) effectively preserves cell structures. This faster method reduces processing time while maintaining high-quality results for biological samples.

Area of Science:

  • Cell Biology
  • Microscopy Techniques

Background:

  • Conventional transmission electron microscopy (TEM) protocols involve lengthy fixation, washing, dehydration, and infiltration steps.
  • Optimizing these steps can significantly reduce experimental time and potentially improve sample quality.

Purpose of the Study:

  • To evaluate the performance of a moderately shorter fixation protocol for TEM.
  • To assess the preservation of cell structure and organelles using this expedited method.

Main Methods:

  • Murine peritoneal and mesenteric lymph node cells were processed using a modified, time-reduced fixation protocol.
  • The quality of cell structure and organelle preservation was analyzed post-processing.

Main Results:

  • The shorter fixation protocol demonstrated good preservation of various cell structures.
  • Organelle integrity was maintained, indicating successful ultrastructural analysis.

Conclusions:

  • A moderately shorter fixation protocol is a viable alternative for TEM sample preparation.
  • This optimized protocol can save time without compromising the quality of ultrastructural analysis.

Transmission Electron Microscopy

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 keV in...

Preparation of Samples for Electron Microscopy

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...
Super-resolution Fluorescence Microscopy01:37

Super-resolution Fluorescence Microscopy

Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been developed.

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.
