ProteomicsChemical labeling for fine mapping of IgG N-glycosylation by ETD-MS
Immunoglobulin G (IgG), which contains four subclasses (IgG1-4), is one of the most important class of glycoproteins in immune system. Because of its importance in immune system, a steady increase of interest in developing IgG as biomarker or biotherapeutic agents for the treatment of diseases has b...

ProteomicsSAPT, a fast and efficient approach for simultaneous profiling of protein N- and C-terminome
Protein termini play pivotal roles in various biological processes. Although a series of terminomic strategies have been proposed for the analysis of protein N-termini or protein C-termini separately, few can analyze both ends of proteins at the same time. Herein, we developed a workflow, termed Sim...

ProteomicsNAPT, an unbiased approach for sequential analysis of protein N- and C- terminome
Robust analysis of both protein N- and C-termini can reveal novel N- and C-degrons that modify protein stability and shape the eukaryotic proteome. Herein, we designed a workflow, termed LysargiNase-assisted Analysis of Protein N- and C-Terminome (NAPT) by sequential and selective separating N- and ...

ProteomicsFluoroTRAQ: Quantitative Analysis of Protein S-nitrosylation through Fluorous Solid-phase Extraction Combining with iTRAQ by Mass Spectrometry
S-nitrosylation is an important post-translational modification which occurs on cysteine in organisms. S-nitrosylation regu-lates signal transduction in many cell processes and aberrant S-nitrosylated (SNO-) proteins are closely related to cardiovas-cular and neurological diseases. However, quantita...

Proteomicsone step carboxyl group isotopic labeling for quantitative analysis of N-glycopeptide by Mass Spectrometry
Glycosylation is one of the most common and important post-translational modifications. Quantitative analysis of intact N-glycopeptides is critical to understand the role of protein glycosylation in physiological and pathological processes. In this work, we developed a novel approach called methylam...

ProteomicsHigh throughput quantitative analysis of site-specific N-glycosylation reveals glyco-signatures for diagnosis of liver disease
Glycosylation influences diverse life processes and changes in pathological processes. The glycoproteomic has been recognized as a hot area to screen markers as altered glycosylation is a universal feature of cancer cells. However, the high throughput screening of glycosylation markers from a large ...

ProteomicsA Chemical Proteomics Approach for Global Mapping of Functional Lysines on Cell Surface of Living Cell
Cell surface proteins are responsible for many crucial physiological roles, and they are also the major category of drug targets as the majority of therapeutics target membrane proteins on the surface of cells to alter cellular signaling. How-ever, despite its great significance, ligand discovery ag...

ProteomicsHigh-Throughput Intact Glycopeptide Quantification Strategy with Targeted-MS (HTiGQs-Target) Reveals Site-Specific IgG N-Glycopeptides as Biomarkers for Hepatic Disorder Diagnosis and Staging
We developed a high-throughput targeted quantification strategy for intact glycopeptides (HTiGQs-Target) to diagnose and differentiate the malignancy of liver diseases. The method involves two-step labeling. This step derivatization makes the same parent ions in different samples produce sufficient ...
