ProteomicsEvaluating the performance of photon- and electron-based fragmentation methods in Omnitrap-LCMS analysis of N-glycopeptides
To date, collision-induced dissociation and methods based on electron transfer dissociation are considered the standard approaches for the mass spectrometry analysis of N- and O-glycopeptides, respectively, allowing for identification of both peptide and glycan compositions. In recent years, alterna...

ProteomicsUVPD of peptides modified with N-terminal UV-absorbing chromophores
Ultraviolet photodissociation (UVPD) has emerged as a powerful alternative to conventional collision-induced dissociation (CID) for peptide and protein sequencing in mass spectrometry–based proteomics. However, UVPD efficiency depends on the presence of UV-absorbing chromophores within analytes.The ...

ProteomicsTop-Down Mass Spectrometry of a Clinical Antibody Light Chain Using the Omnitrap-Orbitrap-Booster Platform
The Omnitrap-Orbitrap-Booster (OOB) mass spectrometry (MS) platform was developed to advance top-down (TD) MS analysis of proteins. It integrates a multimodal tandem mass spectrometry (MS/MS) ion trap system (OmnitrapTM), a high-resolution Orbitrap Fourier transform mass spectrometer (FTMS), and a h...
