MetabolomicsGlobal 13C tracing and metabolic flux analysis of intact human liver tissue ex vivo
Liver metabolism is central to human physiology and influences the pathogenesis of common metabolic diseases. Yet, our understanding of human liver metabolism remains incomplete, with much of current knowledge based on animal or cell culture models that do not fully recapitulate human physiology. He...

ProteomicsHuman serum N-linked intact glycopeptides LC-MS/MS
Large-scale identification of N-linked intact glycopeptides by liquid chromatography coupled tandem mass spectrometry (LC-MS/MS) in human serum is challenging due to the wide dynamic range of serum protein abundances, the lack of a complete serum N-Glycan database and the existence of non-specifical...

MetabolomicsUntargeted LC-MS metabolomic studies of Asteraceae species to discover inhibitors of Leishmania major dihydroorotate dehydrogenase

INTRODUCTION: Interesting data about the family Asteraceae as a new source of Leishmania major dihydroorotate dehydrogenase (LmDHODH) inhibitors are presented. This key macromolecular target for parasites causing neglected diseases catalyzes the fourth reaction of the de novo pyr...

ProteomicsMulti-level – Intact, Subunits, and Peptides – Characterization of Antibody-Based Therapeutics by a Single-Column LC-MS setup
A comprehensive characterization of biotherapeutics, mandated by regulatory authorities, require analyses of a protein drug at multiple structure levels. Such multi-level characterization can be performed by mass spectrometry (MS), with established conventional MS-based assays of product quality att...

MetabolomicsUntargeted Metabolite Profiling (LC-MS) of Root Exudates of Grassland Species

Plants exude a diverse cocktail of metabolites into the soil as response to exogenous and endogenous influences. So far, root exudates have only been studied under artificial conditions due to methodological difficulties. In this study, each five perennial grass and forb species were investigated...

ProteomicsGlobal quantification of intact proteins via chemical isotope labeling and mass spectrometry
Although thousands of intact proteins can be feasibly identified in recent years, global quantification of intact proteins is still challenging. Herein, we develop a high-throughput strategy for global intact protein quantification based on chemical isotope labeling. The isotope incorporation effici...

ProteomicsMALDI-MS Profiling of Intact Blood Proteins without the Need for Freezing - Dried Serum Spots as Future Clinical Tools for Patient Screening
To open new ways for MALDI-MS-based patient screening, blood serum is the most preferred specimen because of its richness in patho-physiological information and due to ease of collection. To overcome deleterious freeze / thaw cycles and to reduce high costs for shipping and storage, we sought to dev...
