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 ...

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...

ProteomicsCapillary zone electrophoresis-tandem mass spectrometry as an alternative to liquid chromatography-tandem mass spectrometry for top-down proteomics of histones with the identification of over 1000 histone proteoforms
Top-down proteomics (TDP) is an ideal approach for deciphering the histone code and it routinely employs reversed-phase liquid chromatography (RPLC)-tandem mass spectrometry (MS/MS). Here we present capillary zone electrophoresis (CZE)-MS/MS via the electro-kinetically pumped sheath-flow CE-MS inter...
