title: Method for purification of fluorescence-labeled oligosaccharides by pyridylamination.
abstract: We developed a convenient method for purification of PA-oligosaccharides to remove contaminants originating from natural fluorescent materials, and excess reagents as well as by-products of tagging reactions in glycan analysis. The method, using a C18-cartridge, is simple and powerful to remove them. Several examples of experiments that showed the usefulness of this purification method are described in this report.
