Abstract

The several different core regions of O-linked chains (Chapter 105) can be further extended by Gal and GlcNAc containing backbones or by addition of blood group antigen-type glycosylation and the presence of sialic acid or sulfate. We sought a universal column that can be applied with high resolution to the various oligosaccharide alditols released from glycoproteins by β-elimination (see Note 1) and have pioneered (1,2) the use of porous graphitized carbon (PGC). This is an alternative to C18 reversed-phase HPLC and normal-phase amino-bonded columns, which can be used together in the presence and absence of high-salt buffers (3).
