In this work, for the first time, hydrazide functionalized PAMAM was designed and synthesized for efficient and selective enrichment of N-linked glycopeptides from complex biological samples using FASP (filter-aided sample preparation) mode.
Selective capture of protein C-termini is still challenging in view of the lower reactivity of the carboxyl group relative to amino groups and difficulties in site-specifically labeling the carboxyl group on the C-terminus rather than that on the side chains of acidic amino acids. For highly efficient purification of C-terminus peptides, a novel positive… (More)
The accuracy of current biomarkers for the diagnosis of hepatocellular carcinoma (HCC), especially chronic Hepatitis B Virus (HBV)-related HCC, is limited. Recent progress in glycoproteomics has provided a novel platform for screening novel serological biomarkers of HCC. In this study, lectin affinity chromatography by Maackia amurensis lectin (MAL) and… (More)
Post-translational modifications (PTMs) are covalent additions of functional groups to proteins and are known to play essential roles in biological processes. Covalently attached PTMs are usually present at substoichiometric levels, implying that a PTM proteome is often present in only a small fraction of the entire proteome. The low abundance of PTMs… (More)
