MetabolomicsElucidations on the structures of some putative flavonoids identified in postharvest withered grapes (Vitis vinifera L.) by quadrupole time-of-flight mass spectrometry
Grape dehydration is an oenological process used for production of high-quality reinforced and sweet wines. High-resolution mass spectrometry (ultrahigh-performance liquid chromatography/quadrupole time-of-flight [UHPLC/QTOF]) was used to deepen the characterization of some flavonoids previously pro...

MetabolomicsTime-resolved decoding of metabolic signatures of in vitro growth of the hemibiotrophic pathogen Colletotrichum sublineolum
Metabolomics has emerged as a powerful approach to comprehensively interrogate cellular biochemistry. As such, we applied an untargeted liquid chromatography-mass spectrometry metabolomic strategy to elucidate metabolome changes in the anthracnose-causing hemibiotrophic sorghum pathogen, Colletotric...

ProteomicsCapillary Zone Electrophoresis-Electron-Capture Collision-Induced Dissociation on a Quadrupole Time-of-Flight Mass Spectrometer for Top-Down Characterization of Intact Proteins
Mass spectrometry (MS)-based denaturing top-down proteomics (dTDP) requires high-capacity separation and extensive gas-phase fragmentation of proteoforms. Herein, we coupled capillary zone electrophoresis (CZE) to electron-capture collision-induced dissociation (ECciD) on an Agilent 6545 XT quadrupo...
