Synthesis of 3,6-branched arabinogalactan-type tetra- and hexasaccharides for characterization of monoclonal antibodies

Synthesis of tetra- and hexasaccharides built up from a β-(1→6)-linked galactopyranosyl backbone with arabinofuranosyl side chains at position 3 and with a 3-aminopropyl spacer related to arabinogalactans is described. These oligosaccharides were prepared for investigation of monoclonal antibodies raised against arabinogalactan proteins (AGPs) from pressed juice of Echinacea purpurea.
