  • Title: A differential stain for neuronal nucleoli in unfixed cryostat sections.
    Author: Sandoz PA, Meier E.
    Journal: Stain Technol; 1978 Jul; 53(4):195-7. PubMed ID: 83689.
    Abstract:
    The Klüver-Barrera procedure, using luxol fast blue and cresyl violet for a combined nissl and myelin stain, was adapted to unfixed cryostat sections. Neuronal nucleoli appeared as distinct dark blue structures. The color contrast between violet Nissl substance and the nucleoli facilitated their recognition in human and in rat central nervous systems. This modified staining procedure enabled us to combine a counting of nerve cells with a histochemical investigation by applying each technique to a different set of sections cut from the same block of unfixed, frozen brain tissue.
