Summary
Picric acid-formaldehyde (PAF) fixative has been compared to other fixatives commonly employed in electron microscopy in order to check its ability to be used in immunoferritin studies. From the results obtained PAF seems to offer very good preservation of the tissue fine structure together with satisfactory detection of immune reactions at ultrastructural level.
