Immunocytochemistry performed on paraffin or cryosections is often hampered by poor morphology. Epoxy sections, in contrast, generally retain well-preserved tissue architecture. Immunocytochemistry, however, on epoxy-embedded sections is difficult due in part to the plastic itself and to the fixation conditions.

Galactocerebroside (GalC) and sulfatide are major constituent lipids in vertebrate myelin. Their precise immunolocalization in electron microscopy so far has been hampered by the fact that lipids are not immobilized by chemical fixation and thus get extracted during dehydration with
