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...

ProteomicsSOD cambium Proteomics Data - OnPLS integration of transcriptomic, proteomic and metabolomic data shows multi-level oxidative stress responses in the cambium of transgenic hipI- superoxide dismutase Populus plants
Reactive oxygen species (ROS) are involved in the regulation of diverse physiological processes in plants, including various biotic and abiotic stress responses. Thus, oxidative stress tolerance mechanisms in plants are complex, and diverse responses at multiple levels need to be characterized in or...

MetabolomicsA combined direct infusion/reversed phase chromatography – high resolution mass spectrometry workflow for accurate absolute lipid quantification with 13C- internal standards
We propose a fully automated novel workflow for lipidomics based on flow injection, followed by liquid chromatography-high-resolution mass spectrometry (FI/LC-HRMS). The workflow combined in-depth characterization of the lipidome achieved via reversed-phase LC-HRMS with absolute quantification by us...

ProteomicsSingle-shot top-down proteomics with capillary zone electrophoresis-electrospray ionization-tandem mass spectrometry for identification of nearly 600 Escherichia coli proteoforms
Capillary zone electrophoresis-electrospray ionization-tandem mass spectrometry (CZE-ESI-MS/MS) has been recognized as an invaluable platform for top-down proteomics. However, the scale of top-down proteomics from CZE-MS/MS is still limited due to the low loading capacity and narrow separation windo...

ProteomicsChemical derivatization of histones for LC-MS/MS analysis
Histone lysine methylation is an important post-translational modifications (PTMs) that plays critical roles in numerous biological processes with abnormal histone lysine methylation having been associated with developmental defects and human diseases. The primary amine of all lysine residues can be...

MetabolomicsEmerald ash borer (Agrilus planipennis) infestation bioassays and metabolic profiles of green ash (Fraxinus pennsylvanica) provide evidence for an induced host defensive response to larval infestation

INTRODUCTION: Larvae of the invasive emerald ash borer [EAB, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae)], kill over 99% of green ash (Fraxinus pennsylvanica Marshall) trees they infest, yet a small percentage of green ash (“linge...

MetabolomicsBenchmarking non-targeted metabolomics using yeast extract controls

Non-target analysis based on high resolution mass spectrometry calls for quality controls to validate analytical workflows. So far no community-wide used quality control material has been established in metabolomics. In this work, we propose ethanolic yeast extracts derived from Pichia pastoris i...
