An Azocarmine stain for Differential cell Analysis of the rat Anterior Hypophysis

Abstract
A method of staining is descr. which is especially designed to facilitate differentiation of the cell types of the rat anterior hypophysis. Fixation in Zenker-formol soln. is recommended. Prestaining of the nuclei by a short immersion in alum hematoxylin is followed by mordanting in anilin alcohol and a 45-min. period of staining in azocarmine soln. at 60[degree]C. The counterstains, acid green and orange G, are dissolved in clove oil to avoid destaining of the azocarmine.
