This review presents the recent advances of capillary electrophoresis-mass spectrometry (CE-MS) for multilevel proteomics, including technological progress and biological applications. CE-MS has emerged as a valuable alternative to liquid chromatography-mass spectrometry due to its efficient separation and sensitive detection for peptides, proteoforms, and protein complexes.
Multilevel proteomics aims to delineate proteins at the peptide (bottom-up proteomics), proteoform (top-down proteomics), and protein complex (native proteomics) levels. Capillary electrophoresis-mass spectrometry (CE-MS) can achieve highly efficient separation and highly sensitive detection of complex mixtures of peptides, proteoforms, and even protein complexes because of its substantial technical progress. CE-MS has become a valuable alternative to the routinely used liquid chromatography-mass spectrometry for multilevel proteomics. This review summarizes the most recent (2019-2021) advances of CE-MS for multilevel proteomics regarding technological progress and biological applications. We also provide brief perspectives on CE-MS for multilevel proteomics at the end, highlighting some future directions and potential challenges.
