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...

MetabolomicsAutomated, Parallel Mass Spectrometry Imaging and Structural Identification of Lipids
We report a method that enables automated data-dependent acquisition of lipid tandem mass spectrometry data in parallel with a high-resolution mass spectrometry imaging experiment. The method does not increase the total image acquisition time and is combined with automatic structural assignment. Thi...

ProteomicsIdentification of Missing Proteins in Human Olfactory Epithelial Tissue by Liquid Chromatography-Tandem Mass Spectrometry
We performed proteomic analyses of human olfactory epithelial tissue to identify missing proteins using liquid chromatography-tandem mass spectrometry. Using a next-generation proteomic pipeline with a <1.0% false discovery rate at the peptide and protein levels, we identified 3,731 proteins, among ...

MetabolomicsComprehensive High-Resolution Multiple-Reaction Monitoring Mass Spectrometry for Targeted Eicosanoid Assays
Eicosanoids comprise a class of bioactive lipids derived from a unique group of essential fatty acids that mediate a variety of important physiological functions. Owing to the structural diversity of these lipids, their analysis in biological samples is often a major challenge. Advancements in mass ...

MetabolomicsCollected mass spectrometry data on monoterpene indole alkaloids from natural product chemistry research
MIADB: a cumulative collection of 172 tandem mass spectrometry (MS/MS) of a vast array of monoterpene indole alkaloids. Samples were analyzed using an Agilent LC-MS system composed of an Agilent 1260 Infinity HPLC coupled to an Agilent 6530 ESI-Q-TOF-MS operating in positive mode. A Sunfire analytic...

MetabolomicsCoupling between high-resolution mass spectrometry and focalized data-analysis methods provides the identification of new putative glycosidic non-anthocyanic flavonoids in grape

INTRODUCTION: The biochemical diversity of flavonoids is based on glycosylation, methylation, acylation, and many other modifications of the flavonoid backbone. Liquid chromatography coupled to high-resolution mass spectrometry demonstrated to be a powerful approach to gain new i...

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...

ProteomicsOne-dimensional capillary liquid chromatographic separation coupled with tandem mass spectrometry unveils the Escherichia coli proteome on a microarray scale.
We successfully identified the proteome expressed in Escherichia coli (E. coli) cells on a microarray scale using one-dimensional capillary liquid chromatography-tandem mass spectrometry (LC-MS/MS) with a 350 cm long, 100 microm i. d., monolithic silica-C(18) capillary column. E. coli tryptic digest...

TranscriptomicsTranscription profiling of mouse fetal liver feeder layer and endothelial progenitor cells
While others have reported that fetal liver contains a population of endothelial progenitors based on expression of cell surface markers or culture assays, this is the first proof of a CD31+Sca1+ progenitor by demonstrating highly efficient in vivo angiogenesis and a direct connection to the host va...
