Glycomic analysis of s190-HARE. MALDI-TOF mass spectrum of permethylated s190-HARE N-glycans. N-Glycans were derived from the 50% (v/v) acetonitrile fraction from a C18 Sep-Pak. All molecular ions are [M+-Na]+-, and nominal masses of the 12C isotope are shown. The putative structures shown are based on composition, tandem mass spectrometry analysis and knowledge of biosynthetic pathways. Symbol code: Gal (yellow circle), Man (green circle), GlcNAc (blue square), Fuc (red triangle) and NeuAc (purple diamond)
