Characterisation of oligosaccharides from a glycoprotein variant of human serum albumin (albumin Casebrook) using high-performance anion-exchange chromatography and nuclear magnetic resonance spectroscopy.

Abstract excerpt

The characterisation of oligosaccharides present on albumin Casebrook, a glycoprotein variant of human serum albumin, which contains an N-linked oligosaccharide at an attachment site formed by a point mutation of 494 Asp-->Asn, is described. The monosaccharide compositional analysis of purified glycopeptides suggested the presence of complex biantennary carbohydrate structures. The oligosaccharides which were...
