The preservation and contrast of membranous structures in cultured cells using various postfixation procedures prior to embedding have been investigated. These include routine OsO4, ferrocyanide-reduced OsO4, osmium-thiocarbohydrazide-osmium (OTO), and ferrocyanide-reduced osmium-thiocarbohydrazide-ferrocyanide...
