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

Protein complexes represent major functional units for the execution of biological processes. Systematic affinity purification coupled with mass spectrometry (AP-MS) yielded a wealth of information on the compendium of protein complexes expressed in Saccharomyces cerevisiae. However, global AP-MS analysis of
