Louise Royle et al.
Methods in molecular biology (Clifton, N.J.), 347, 125-143 (2006-10-31)
In contrast to the linear sequences of protein and DNA, oligosaccharides are branched structures. In addition, almost all glycoproteins consist of a heterogeneous collection of differently glycosylated variants. Glycan analysis therefore requires high-resolution separation techniques that can provide detailed structural
