ProteomicsLaser capture microdissection-capillary zone electrophoresis-tandem mass spectrometry (LCM-CZE-MS/MS) for spatially resolved top-down proteomics: a pilot study of zebrafish brain
Mass spectrometry (MS)-based spatially resolved top-down proteomics (TDP) of tissues is crucial for understanding the roles played by microenvironmental heterogeneity in the biological functions of organs and for discovering new proteoform biomarkers of diseases. There are few published spatially re...

ProteomicsSpatially resolved top-down proteomics of tissue sections based on a microfluidic nanodroplet sample preparation platform
We demonstrate spatially resolved top-down proteomics (TDP) for proteoform identification and quantification from small sections of rat brain. We used the nanoPOTS (nanodroplet Processing in One pot for Trace Samples) platform, further improving the sample preparation by adding benzonase in the extr...

ProteomicsSpatially-Resolved Top-Down Proteomics of Zebrafish Brain Using Capillary Zone Electrophoresis-Tandem Mass Spectrometry
Understanding region-specific proteoform profiles in the brain is crucial for deciphering neural function and identifying potential therapeutic targets. Here, we present a comprehensive label-free quantitative top-down proteomics (TDP) analysis of distinct zebrafish brain regions using capillary zon...

ProteomicsProteoform Imaging by Combining MALDI MSI and High-sensitivity Top-down Proteomics
Spatially resolved characterization of proteoforms has great potential to significantly advance our understanding of physiological and disease mechanisms. However, it faces challenges regarding throughput and coverage. Herein, we developed a robust method for high-throughput proteoform imaging (HTPi...
