title: Aldehyde Fuchsin staining of pancreatic B cells. Reproducible high-contrast staining of formalin-fixed and paraffin-embedded material.
abstract: The use of Aldehyde Fuchsin for the demonstration of B cell granules in the pancreatic islets on material fixed in formalin and embedded in paraffin has led to variable results. Treatment of such sections for 1 h with Bouin's fluid or 5% glutaraldehyde prior to deparaffinization, however, stabilizes the secretory granules in B cells. In addition, the zymogenic granules of the acinar cells exhibit increased stainability with the permanganate Aldehyde Fuchsin procedure.
