| titleOfInvention | Optimized fragmentation for quantitative analysis of fucosylated n-glycoproteins by lc-ms-mrm |
| abstract | Provided is a sensitive and specific LC-MS-MRM quantification method that distinguishes outer-arm and core fucosylated configurations of N -glycopeptides. Advantage is taken of limited fragmentation of the glycopeptides at low collision energy (collision-induced dissociation) CID to produce linkage-specific Y-ions. These ions are selected as multiple reaction monitoring (MRM) transitions for the quantification of the outer-arm and total fucosylation of 23 glycoforms of 9 glycopeptides in 7 plasma proteins. The method permits quantification of the glycoforms directly in plasma or serum without fractionation of samples or glycopeptide enrichment. A pilot study of fucosylation in liver cirrhosis of hepatitis C virus (HCV) and non-alcoholic steatohepatitis (NASH) etiologies demonstrated that liver cirrhosis is consistently associated with increased outer-arm fucosylation of a majority of the analyzed proteins. The outer-arm fucosyaltion of the A2G2F1 glycoform of the VDKDLQSLEDILHQVENK peptide of fibrinogenwas found to increase more than 10-fold in the cirrhosis patients compared to healthy controls. |
