^aThe compound name, or composition of the OS, is shown as a set of 5 monomers. The following order is as stated with their abbreviations: hex = glucose or galactose; HexNAc = N-acetylhexososamine; Fuc = Fucose; Neu5Ac = N-acetylneuramic acid; and Neu5Gc = N-glycolylneuramic acid (e.g., 3_1_0_0_0 is equal to 3 Hex, 1 HexNAc).

^bMass is the molecular mass measured by the mass spectrometer.

^cRetention time (RT) is the specific elution time from the LC analytical column for each compound.
