Capillary electrophoresis: a superior miniaturized tool for analysis of the mono-, di-, and oligosaccharide constituents of glycan moieties in proteoglycans.
Proteoglycans are a major family of glycoconjugates which participate in and regulate several cellular events and biological functions. Their glycan chains determine their physicochemical and biological properties. Capillary electrophoresis, because of its high resolving power and sensitivity, has been successfully used for the analysis of carbohydrates. The monosaccharide constituents, the disaccharide sulfation pattern, and the uronic acid distribution within glycan chains of proteoglycans determine their interactions with matrix effectors and are responsible for numerous effects. Determination of the chemical composition and identification of key structural components and domains of glycans are, therefore, essential in understanding the biological functions of proteoglycans. In this report an overview of the capillary electrophoresis methods used to analyze and characterize the structure of the glycan chains of proteoglycans is presented.
