N-Glycan Standards

For more details on our glycan standards, or to request a new glycan standard product, please contact us

For glycan masses, see the product pages and our downloadable Excel file listing masses of adduct ions of unlabeled and labeled glycans for mass spectrometry work. The positive mode tab shows glycans labeled by 2-AB, InstantAB, 2-AA, Procainamide and InstantPC. The negative mode tab shows glycans labeled by 2-AB, InstantAB, 2-AA, Procainamide and APTS.
