MetabolomicsMetabolomic profiling of Campylobacter jejuni with resistance gene ermB by ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry and tandem quadrupole mass spectrometry
The metabolome changes of Campylobacter jejuni with resistant gene ermB remain unclear. Here, we described an untargeted metabolomic workflow based on ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry to investigate the metabolites perturbations mediated by erm...

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...

ProteomicsExtending the Separation Space with Trapped Ion Mobility Spectrometry Improves the Accuracy of Isobaric Tag-based Quantitation in Proteomic LC/MS/MS
Two-dimensional separation by nano-LC and trapped ion mobility spectrometry (TIMS) prior to Q-TOF tandem mass spectrometry significantly improves the accuracy of isobaric tag-based quantitation in proteome analysis without the need for additional measurement time for TIMS insertion. The obtained pea...
