ProteomicsQuantitative Native Proteomics by Capillary Zone Electrophoresis-Mass Spectrometry
Accurately measuring protein complex dynamics (i.e., composition and/or abundance changes) in cells is vital for advancing fundamental and translational research. In this work, we present a pilot study establishing capillary zone electrophoresis (CZE)-mass spectrometry (MS) based quantitative native...

MetabolomicsComparative characterization of the infant gut microbiome and their maternal lineage by a multi-omics approach

The human gut microbiome establishes and matures during infancy, and dysregulation at this stage may lead to pathologies later in life. We conducted a multi-omics study comprising three generations of family members to investigate the early development of the gut microbiota. Fecal samples from 20...

ProteomicsCapillary zone electrophoresis-tandem mass spectrometry for top-down proteomics of mouse brain integral membrane proteins
Mass spectrometry (MS)-based top-down characterization of integral membrane proteins (IMPs) is crucial for understanding their functions in biological processes. However, it is technically challenging due to their low solubility in typical MS-compatible buffers. In this work, for the first time, we ...

ProteomicsA simple and efficient approach for preparing cationic coating with tunable electroosmotic flow for capillary zone electrophoresis-mass spectrometry-based top-down proteomics
Capillary zone electrophoresis-tandem mass spectrometry (CZE-MS/MS) has become a valuable analytical technique in top-down proteomics (TDP) in recent years. CZE-MS/MS-based TDP typically employs separation capillaries with neutral coatings (i.e., linear polyacrylamide, LPA). However, issues related ...

ProteomicsSolid phase microextraction-aided capillary zone electrophoresis-mass spectrometry: ready for bottom-up proteomics of single human cells
Capillary zone electrophoresis-mass spectrometry (CZE-MS) has been recognized as a valuable technique for proteomics of mass-limited biological samples (i.e., single cells) due to its high efficiency and high sensitivity for peptide separation and detection. However, its broad adoption for single ce...
