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…
