ProteomicsCellular ADP-ribosylome characterization with HCD and EThcD
Protein ADP-ribosylation is a post-translational modification involved in important physiological and pathological processes. Here, we present an optimized method using the Orbitrap Fusion Tribrid mass spectrometer, which drastically improves the overall ADP-ribosylation site localization score and ...

ProteomicsSite-specific N-glycosylation Characterization of Micro Disease-related Proteins Based on EThcD-sceHCD-MS/MS
Monoclonal immunoglobulin produced by clonal plasma cells is the main cause in multiple myeloma and monoclonal gammopathy of renal significance. Because of the complicated purification method and the low stoichiometry of purified protein and glycans, site-specific N-glycosylation characterization fo...

ProteomicsComprehensive human plasma N-glycoproteome profiling based on EThcD-sceHCD-MS/MS
N-glycoproteins are involved in various biological processes. More than one-third of plasma tumor protein biomarkers approved by the Food and Drug Administration (FDA) are glycoproteins which would enhance the specificity and/or sensitivity of cancer diagnosis. Therefore, the characterization of pla...

Site-specific N-glycosylation characterization requires intact N-glycopeptide analysis based on suitable tandem mass spectrometry (MS/MS) method. Electron-transfer/higher-energy collisional dissociation (EThcD), stepped collision energy/higher-energy collisional dissociation (sceHCD), and higher-ene...

ProteomicsConjugation site characterization of antibody–drug conjugates using electron-transfer/higher-energy collision dissociation (EThcD)
Antibody–drug conjugates (ADCs) are formed by binding of cytotoxic drugs to monoclonal antibodies (mAbs) through chemical linkers. A comprehensive evaluation of the critical quality attributes (CQAs) of ADCs is vital for drug development but remains challenging owing to ADC structural heterogeneity ...

ProteomicsIncreased EThcD efficiency on the hybrid Orbitrap Excedion Pro Mass Analyzer extends the depth in identification and sequence coverage of HLA class I immunopeptidomes
Gaining a complete and unbiased understanding of the non-tryptic peptide repertoire presented by HLA-I complexes by LC-MS/MS is indispensable for therapy design for cancer, autoimmunity and infectious diseases. A serious concern in HLA peptide analysis is that the routinely used, collision-based fra...
