ProteomicsHuman serum N-linked intact glycopeptides LC-MS/MS
Large-scale identification of N-linked intact glycopeptides by liquid chromatography coupled tandem mass spectrometry (LC-MS/MS) in human serum is challenging due to the wide dynamic range of serum protein abundances, the lack of a complete serum N-Glycan database and the existence of non-specifical...

ProteomicsLarge scale intact glycopeptide identification by Mascot database search
We present the adaptability of Mascot search engine for automated identification of intact glycopeptide mass spectra. The steps involved in adopting Mascot for intact glycopeptide analysis include: i) assigning unique one letter codes for monosaccharides, ii) linearizing glycan sequences and iii) pr...

ProteomicsAn automated intact glycopeptide enrichment method for serum site-specific N-glycoproteomic analysis
We developed an automated glycopeptide enrichment method for the analysis of serum site-specific N-glycoproteome. This automated method allowed for processing one sample within 20 min. It showed higher enrichment specificity, more intact glycopeptide identifications, and better quantitative reproduc...

ProteomicsComparison of Intact Glycopeptide Enrichment Methods Using Strong Anion Exchange and Hydrophilic Interaction Liquid Chromatography
Heterogeneity of protein glycosylation poses great challenge for analysis that is key to un-puzzle systems glycobiology in diseases. Resolving this conundrum requires global enrichment of glycopeptides for identification and quantitation. To this aim, hydrophilic interaction chromatography (HILIC) h...

ProteomicsDirect glycan structure determination of intact N-linked glycopeptides by low-energy collision-induced association tandem mass spectrometry and predicted spectral library searching
Intact glycopeptide MS analysis to reveal site-specific protein glycosylation is an important frontier of proteomics. However, computational tools for analyzing MS/MS spectra of intact glycopeptides are still limited and not well-integrated into existing workflows. In this work, a novel computationa...
