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 ...
