Relative abundance of the glycans detected in the HILIC chromatograms.

The relative glycan abundance was calculated as the area under the peak attributed to the glycan, divided by the sum of the areas of all the peaks detected in the chromatogram. N-glycans were attributed to the peaks detected by comparison of the peaks glucose units (GU) values to database. The values in bold correspond to abundances ≥10%. The symbolic representation of the sugars is: N-acetylglucosamine (blue square), mannose (green circle), galactose (yellow circle), N-acetylneuraminic acid (α2,6) (pink diamond), N-acetylneuraminic acid (α2,3) (blue diamond) and fucose (red triangle). pr.: presumably, u.g.: undetermined glycan.
