Description

Application

Alcian Blue 8GX has been used for the staining of sulfated proteoglycans in murine MPC (mesenchymal progenitor cell) nodule. It has been used for the staining of sulfated proteoglycans in bovine articular chondrocytes.

Biochem/physiol Actions

Alcian Blue 8GX is a cationic dye. It forms insoluble complexes with acidic glycosaminoglycans, thereby helping in the quantitative determination of glycosaminoglycans. It is also used for the staining of bone and cartilage.

Suitability

Certified for use in staining in Mowry′s pH 2.5 method, in Scott′s pH 5.7 method, and in Kreyberg′s method for keratin and mucin.
