Glycan-targeting affinity chromatography systems are becoming increasingly important as tools in the purification, enrichment, and identification of glycoproteins. The great advantage of this strategy is that immobilized lectin and antibody selectors allow specific glycan structures to be matched with a particular protein. A problem with single column affinity chromatography is how to obtain information on glycan diversity within the oligosaccharide portions of captured glycoproteins. Although all the glycoprotein species bearing a particular glycan feature will be captured by an affinity column, there is no way of knowing whether the ligand being targeted appears alone or co-resides with a series of other glycan features in the same oligosaccharide conjugate. The utility of serial affinity columns was examined in determining whether individual glycan structures appear alone or together with other glycans in specific proteins. Serial affinity chromatography (SAC) can be a valuable tool in recognizing diversity in protein glycosylation, especially when the order of columns in the SAC series is varied. Two clear types of diversity were recognized. One is the independent occurrence of different affinity targetable glycan features in the same glycoprotein. The second is the case in which multiple targetable glycan features were co-resident in the same glycoprotein. The great advantage of this method is that it couples easily with current methods used in glycoproeomics.
