The predicted and observed m/z values for pyridylaminated neutral N-glycans isolated by RP-amide HPLC and analysed by MALDI-TOF MS are listed along with elution times (in glucose units, g.u.) and proposed structures according to the pictorial nomenclature of the Consortium for Functional Glycomics, supplemented in certain cases with the Schachter-style nomenclature (MM, MGn, GnM, etc). A, F or A/F indicates a glycan detected only in the PNGase A (post PNGase F) pool, PNGase F pool or both; nd, not detected in fractions of either species. Estimation of glycan amounts is indicated (scale from ‘+++’ through to ‘trace’), whereby ‘+++’ is for the major components present in the HPLC fractions with the highest fluorescence intensity.
