Brief Introduction to Contrasting for EM Sample Preparation

Since the contrast in the electron microscope depends primarily on the differences in the electron density of the organic molecules in the cell, the efficiency of a stain is determined by the atomic…

Brief Introduction to Glass Knifemaking for Electron and Light Microscope Applications

Glass knives are used in an ultramicrotome to cut ultrathin slices of samples for electron and light microscope applications. For resin and for cryo sections (Tokuyasu samples) the knife edge must be…

Perusing Alternatives for Automated Staining of TEM Thin Sections

Contrast in transmission electron microscopy (TEM) is mainly produced by electron scattering at the specimen: Structures that strongly scatter electrons are referred to as electron dense and appear as…

Brief Introduction to Critical Point Drying

One of the uses of the Scanning Electron Microscope (SEM) is in the study of surface morphology in biological applications which requires the preservation of the surface details of a specimen. Samples…
