Formalin fixed, glycol methacrylate-embedded tissue samples can easily be used for immunofluorescent studies by direct and indirect fluorescein isothiocyanate staining after treatment with protease V to unmask antigenicity. It is, therefore, possible to use serial 2-micron glycol methacrylate-embedded sections for immunologic studies, as well as conventional and special stains.
