title: Synthesis of oligosaccharides on soluble high-molecular-weight branched polymers in combination with purification by nanofiltration.
abstract: [structure: see text] An efficient approach for polymer-supported oligosaccharide synthesis is described whereby branched and high-molecular-weight PEG derivatives are used in combination with purification by nanofiltration. This methodology was applied to the preparation of a tetraglucoside and the tumor-associated antigen Le(x).
