Compositional analysis glycoprotein glycan compositions released by PNGase F treatment . a. EIC of labeled N-glycans (m/z 1000-1600). b.) Mass spectrum of tetraplex labeled α-1- acid glycoprotein glycans (d0: human; d4: sheep; d8: bovine; d12: baboon) showing inserts for four N-glycan compositions. c.) Percent relative abundances per μg protein of reducing end labeled compositions. N-Glycan structure are listed using the following abbreviations: BiAn, Hex5HexNAc4; TriAn, Hex7HexNAc5; TetraAn, Hex9,HexNAc6.
