title: High-performance liquid chromatography of urinary oligosaccharides in the diagnosis of glycoprotein degradation disorders.
abstract: Urinary oligosaccharides can be separated by high-performance anion-exchange chromatography using a Dionex CarboPac PA1 column, elution with aqueous sodium hydroxide and sodium acetate solutions and detection by pulsed amperometry. Each of the urines of patients with glycoprotein degradation disorders yielded a pattern of oligosaccharide excretion unique for that disorder, facilitating an unambiguous diagnosis. The method is sensitive (10 microliters of urine required) and fast (40 min).
