title: Analysis of the oligosaccharide units of xyloglucans by digestion with isoprimeverose-producing oligoxyloglucan hydrolase followed by anion-exchange chromatography.
abstract: A method for rapidly identifying six of the most commonly found xyloglucan oligosaccharide units, XXXG, XLXG, XXLG, XLLG, XXFG, and XLFG was developed by high-performance anion exchange chromatography (HPAEC) with pulsed amperometric detection (PAD) before and after digestion with purified isoprimeverose-producing oligoxyloglucan hydrolase (IPase). Using this method, the compositions of oligosaccharide units of soybean and mung bean xyloglucans were re-examined. Significant amounts of oligosaccharides that have not previously been reported to be oligosaccharide units of soybean and mung bean xyloglucans were found.
