HILIC for Released Glycans

Released N-Glycan Columns

Waters ACQUITY UPLC and XBridge Glycan BEH Amide 130Å Columns are best suited for the analysis of released, N-labeled glycans using pre-column labeling with 2-AB, 2-AA, or Waters innovative and enabling RapiFluor-MS reagent. Each batch our Glycan BEH Amide 130Å chemistry is specifically QC tested with a complex mixture of 2-AB labeled glycans from a mAb digest to help ensure consistent column performance in validated methods.

The image to the right shows the N-linked glycans from pooled human IgG contain high mannose as well as neutral, and sialylated complex structures. The chromatogram shows 35 minutes of a one hour analysis. This challenging sample includes high mannose, bisecting GlcNAc and sialylated species.
