Poststaining Sections for Electron Microscopy

Abstract

“Dirt” on electron microscopic sections can generally be avoided by the simple strategem of preventing dry sections from coming in contract with any solution with a dirty surface layer. Wet sections can be pushed through the surface layer of such solutions without ill effect. The first and last solutions to touch a section must be dean, preferably distilled water from a plastic wash bottle.
