Electron Microscopy by the numbers

From the moment scientists trained the first light microscopes on biological tissues, no laboratory has been complete without them. The development of electron microscopes with their highly increased resolving power—up to two million times the magnification of a standard light microscope—opened new windows into cells’ architecture enabling scientists to view objects in greater magnification than ever before.

Instead of light, electron microscopes use a focused beam of high voltage electrons to generate extraordinarily detailed and striking images. In addition to being highly trained microscopists, members of the Stowers electron microscopy core provide skilled assistance in preparing specimens for analysis including chemical fixation, staining, dehydration, sectioning, freezing and coating.
