title: High-resolution glycoprotein analysis using capillary electrophoresis.
abstract: The high-resolution separation achievable with capillary electrophoresis has been applied successfully to the analysis of glycoproteins. Inherent in the implementation of this technology for glycoprotein analysis is the use of specific buffer additives. Bifunctional cationic reagents, such as simple alkyl chains bearing terminal amino or quaternary ammonium groups, have been particularly useful for the analysis of ovalbumin, an excellent model glycoprotein. Although dynamic coating of the capillary wall and the subsequent decrease in protein-wall interactions in known to be key in the effectiveness of these additives, much remains to be learned regarding the mechanism through which they function.
