This protocol covers the procedure for fixation, embedding and staining of material for examination by transmission electron microscopy (TEM). This includes working with various embedding resins, formvar grids and immunogold labelling.
Oct 4, 2007 · TEM also has an important role in cytopathology. Cells in effusions, like cells in culture, can be readily prepared for TEM. Epithelial cells are easily distinguishable from mesothelial...

The TEM uses a beam of electrons to resolve structures far beyond the resolution of conventional light microscopy (less than 200 nm). Electrons produced by heating a filament (Tungsten or LaB6) at voltages ranging from 60-120kV, are fired towards the sample down a column held under vacuum.
May 19, 2022 · Principle of Transmission Electron Microscope (TEM) The working principle of the Transmission Electron Microscope (TEM) is similar to the light microscope. The major difference is that light microscopes use light rays to focus and produce an image while the TEM uses a beam of electrons to focus on the specimen, to produce an image.
In transmission electron microscopy (TEM), electrons are transmitted through a plastic-embedded specimen, and an image is formed. TEM enables the resolution and visualization of detail not apparent via light microscopy, even when combined with immunohistochemical analysis.
