Histology Special Stains

Special stains employ staining techniques to identify suspected pathogens or demonstrate specific cellular components that aid pathologists in the evaluation of disease states. Sigma-Aldrich offers the most commonly utilized special stain procedures, with reagents available as prepared solutions or in convenient kit form. Many of our special stain kits have microwave applications. For customers wishing to prepare their own staining solutions, Sigma-Aldrich offers the stains and dyes, as well as other chemicals and general purpose laboratory reagents required.
