MALDI-MS of N-glycans (reduced to alditols) from tetramer NA (A) and dimer NA (B), and N-glycans (native, non-modified) from the stalk region of tetramer NA (C) and dimer NA (D). The plausible topology of each peak was proposed based on the bio-synthetic knowledge of N-glycosylation and its m/z value. All ions are single sodium adducts. (* Impurities or possible peptides).
