Abstract:
Microchip electrophoresis is a powerful tool for fast analysis of nucleic acids and has expanded its applicability to the analysis of various biological materials including proteins and carbohydrates. Glycosaminoglycans have intrinsic negative charges, and are good targets for electrophoretic analysis. In the present paper, we developed a method to analyze oligosaccharides and unsaturated disaccharides derived from some glycosaminoglycans after digestion with specific enzymes followed by derivatization with 2-aminoacrydone (AMAC) by reductive amination. The method described here allowed rapid analysis of oligosaccharides derived from glycosaminoglycans within 150 s with high sensitivity. We show an application of the present technique to the glycosaminoglycan analysis in cultured HeLa cells.

SDS-PAGE
A variation of gel electrophoresis, termed polyacrylamide gel electrophoresis (PAGE), is commonly used for separating proteins according to their molecular size by passing them through a polyacrylamide gel. Because of the varying charges associated with amino acid side chains, PAGE can be used to separate intact proteins...
Two-dimensional Gel Electrophoresis
