Fractionation of glycoprotein-derived oligosaccharides by affinity chromatography using immobilized lectin columns.
Lectin affinity column chromatography is becoming a method of choice for the fractionation and purification of oligosaccharides, especially N-linked oligosaccharides. Using lectin affinity, it is easy to separate structural isomers and to isolate oligosaccharides based on specific features. Further, serial lectin column chromatography, when various lectin columns are used at the same time, can afford a very sensitive method for the fractionation and characterization of extremely small amounts of oligosaccharides. Thus, when used in conjunction with other separation techniques, lectin affinity chromatography can help to purify rapidly oligosaccharides and provide substantial information about their structural features.
