Abstract

See full text

A staining technique for specimens which involves the sequential treatment of specimens with periodic or hydrochloric acid, thiocarbohydrazide or thiosemicarbazide, and silver methenamine. The technique, when using periodic acid, provides an excellent stain to evaluate glycomacromolecules and fibrovascular tissue and to conduct a broad spectrum of staining procedures for all modes of microscopy. Use of hydrochloric acid facilitates evaluation of cell nuclear DNA and chromatin.
