The Schiff’s Reagent forms a colorless dialdehyde compound that is transformed to the magenta staining of glycol containing cellular components.4 The chemical properties of Alcian Blue enable the dye to detect weakly acidic mucins in goblet cells. Alcian Blue for PAS, with a pH of 2.5, stains acid mucopolysaccharides blue.5 This kit is optimized for use on BenchMark Special Stains instruments. The reagent is applied to tissue on microscope slides and mixed over the entire specimen.4. Carson F, Hladik C. Histotechnology: A Self Instructional Text, 3rd edition.
