| Application: | Alcian Blue 8GX is used as a heteroglycan stain for neutral, sulfated, and phosphated mucopolysaccharides and glycosaminoglycans in tissues such as cartilage and extracellular matrices. It is also suitable for amyloid staining, cystine following oxidation, and staining mast cells in polychromatic alcian blue-safranine methods. It is also applicable as a microscopic stain for detection of bacterial capsules, and mucin staining of cytological fine-needle aspirates. |
| Biochem/physiol Actions: | Alcian Blue 8GX forms insoluble complexes with acidic glycosaminoglycans, thereby helping in the quantitative determination of glycosaminoglycans. |
| General description: | Alcian Blue 8GX (Cl 74240), also known as Alcian Blue 8GN is a cationic, copper phthalocyanine dye. |
