AN71993: Profiling Galactosyloligosaccharide-Containing Samples by High-Performance Anion-Exchange Chromatography with Pulsed Amperometric Detection (HPAE-PAD) Be the first to rate this application

Description

GOS occur naturally in the milk of many animals including humans, cows, and wallabies. GOS are primarily composed of galactose and often terminate with a glucose residue at the reducing end. These carbohydrates are enzymatically produced by transgalactosylation reactions of lactose catalyzed by β-galactosidases and give rise to galactose oligomers. Separation of individual oligosaccharides in GOS was achieved on a Thermo Scientific™ Dionex™ CarboPac™ PA200 column. Oligosaccharide detection was by PAD with a gold working electrode, and therefore no sample derivation was required.
