Unconventional application of standard light and electron immunocytochemical analysis to aldehyde-fixed, araldite-embedded tissuesDL Hogan and GH Smith
A simple procedure for the immunocytochemical analysis of glutaraldehyde/formaldehyde-fixed, Araldite- or Epon-embedded tissues by either light or electron microscopy is presented. Retention of immunoreactive antigen in deplasticized sections was achieved by use of a low concentration of glutaraldehyde in the fixative in combination with a seldom-used plastic solvent. This protocol produced good ultrastructural preservation in tissues and large, high-quality, 2- micrometers thick, plastic-free sections. These semithin sections provided a level of structural and antigenic preservation, image resolution, and labeling intensity that surpassed all other conventional sectioning methods used for immunocytochemistry. The capacity to use a single tissue sample in studies designed for light and electron immunocytochemistry, in conjunction with existing autoradiographic and cytochemical techniques, makes this a very desirable method for routine tissue preparation in research and clinical applications.
