A reliable method for electron microscopic examination of specific areas from paraffin-embedded tissue mounted on glass slides.

A reliable method for electron microscopic examination of specific areas from paraffin-embedded tissue mounted on glass slides. Am J Clin Pathol 70: 697--699, 1978. A method to embed and cut tissue mounted on ordinary glass histologic preparations for electron microscopic observations is described. The cover slip is removed by immersing the slide in xylene for a few minutes to several hours. After the cover slip is removed, the tissue is fixed in osmium tetroxide, dehydrated, and embedded in epoxy resins by inverting a BEEM capsule filled with the resin on a selected area of the slide. After polymerization, thin sections are obtained and observed with the electron microscope with good results.
