title: Characterization of O-linked saccharides on glycoproteins.
abstract: Recombinant and native proteins of Pichia pastoris can be O-mannosylated on serine and threonine residues, allowing further elongation reactions to generate short O-linked oligosaccha-rides of mannose. Methods for release from the protein with alkaline beta-elimination with or without reduction of the released saccharides, and for subsequent chromatographic and enzymatic characterization of these saccharides are described.
