英文摘要	an amine chemistry method was developed for the extraction of n-glycopeptides using amine-functionalized beads for glycoproteomics analysis. two reductive amination reactions between primary amine and aldehyde were employed in this approach. the first one was to block the primary amines in the peptides by addition of formaldehyde and sodium c-yanoborohydride into the peptide sample, and the second one was to couple the glycopeptides onto solid phase beads by incubating the glycopeptides containing aldehyde groups (oxidized by periodate) with the amine-functionalized beads in the presence of sodium cyanoborohydride. it was demonstrated that the blocking of primary amines in the peptides by the first reductive amination reaction prior to the periodate oxidation made the amine chemistry method very efficient and sensitive. this new method was validated by analysis of glycoprotein standards as well as proteome samples. it was found that this new method led to significant increase in the identification of n-glycosites compared with the conventional hydrazide chemistry method.
