AU72829: HPAE-PAD Analysis of N-linked Glycans: Improving Glycan Resolution Be the first to rate this application


This application update demonstrates improved resolution of sialylated N-glycans on Thermo Scientific™ Dionex™ CarboPac™ PA200 columns. Starting with a recently described method, changes to elution conditions were tested to improve resolution of sialylated N-glycans enzymatically released from four different glycoproteins. Separations were first evaluated on the analytical format (3 × 250 mm column). Next, the possibility that a shorter column, such as a guard column, would allow significantly improved throughput was evaluated. Finally, a narrow bore format 1 × 250 mm column was tested.
