The Colloidal Iron Stain Kit is designed for the histological visualization of acid mucopolysaccharides. In some cases the Alcian Blue pH 2.5 stain kit (Item#: AFR) proves to be a much more reliable and sensitive option for staining Acid Mucopolysaccharides. We would recommend this kit if the colloidal iron staining is not satisfactory.
Acid Mucopolysaccharides: Bright Blue
Collagen: Shades of Red
