title: Glycosaminoglycans: oligosaccharide analysis by liquid chromatography, capillary electrophoresis, and specific labeling.
abstract: Glycosaminoglycans (GAGs) are a class of biopolymers that include chondrotin sulfate, dermatan sulfate, keratan sulfate, hyaluronic acid, heparin, and heparan sulfate. The GAGs are linear polysaccharides that are microheterogeneous in composition and polydisperse in size. Because they have the most complex structures, this article is aimed at describing a step-by-step procedure for processing and analyzing heparin and heparan sulfate-derived oligosaccharides, although the basic protocols and procedures apply equally well to other members of the GAG family. The methods described in this manuscript include the preparation of oligosaccharides through enzymatic depolymerization, size fractionation by preparative scale size-exclusion chromatography (SEC), and disaccharide isomer analysis by reverse-phase ion-pair high-performance liquid chromatography (RPIP-HPLC) and capillary electrophoresis (CE).
