A sensitive and versatile method for the qualitative and quantitative determination of glycosaminoglycans (GAGs) is described. An enriched GAG fraction was subjected to nuclease enzyme treatment and to an appropriate sequence of GAG degrading enzymes-Streptomyces hyaluronidase, chondroitinase AC and ABC, and endo-β-d-galactosidase-and nitrous acid treatment. To determine the result of each degradative procedure, the remaining GAG polymers were subjected to cellulose acetate electrophoresis. The combination of sequential degradation and the monitoring of each step by electrophoresis and densitometry permitted the identification and quantitation of all the GAGs on a microscale basis.
