Identification of bifucosylated glycoforms using low ‐energy CID spectra
AbstractWe have used tandem mass spectrometry (MS/MS) ‐based analysis of glycopeptides in order to identify the composition and structure of rare glycoforms. The results illustrate utility of low‐energy MS/MS for structure identification. We have shown the presence of bifucosylated and trifucosylated glycoforms in human α‐1‐acid glycoprotein ( AGP), a major plasma glycoprotein. Fucosylation in the case of AGP always occurs on the antennae; core fucosylation was not observed.
