Alcian Blue is a polyvalent, basic, water soluble dye that derives its blue color from the copper phthalocyanine group which is modified with cationic solubilizing agents.3,5 During this reaction, salt linkages are formed between Alcian Blue and the acid groups of the acid mucopolysaccharides, staining them blue. The Nuclear Fast Red Counterstain is applied to provide a pink contrasting background.This kit is optimized for use on BenchMark Special Stains instruments. The reagents are applied to tissue on microscope slides and mixed over the entire specimen.3. Scott JE. Alcian dyes: I.C.I. cease manufacture and release details of composition.
