Figure 1. Representative MALDI-FTICR mass spectra of the three different fractions (10% (A), 20% (B) and 40% (C)).
The peaks of highest abundance have been structurally annotated with putative structures in terms of N-acetylglucosamine, mannose, galactose, fucose and N-acetylneuraminic acids. No linkage information is obtained; therefore putative linkages are displayed.
