Spatially resolved proteomics is an emerging approach, however, it remains technically challenging due to the complexity of the tissue microsampling techniques and mass spectrometry analysis of nanoscale specimen volumes. Here, we describe an expansion proteomics method ProteomEx, a combination of t...

Proteomic data from technical developments of a nanoPOTS-based spatially resolved proteome profiling of <200 cells from tomato fruit pericarp.

Here we present an approach to identify N-linked glycoproteins and deduce their spatial localization using a combination of MALDI N-glycan MSI and spatially-resolved glycoproteomics. We subjected glioma biopsies to on-tissue PNGaseF digestion and MALDI-MSI and found that the glycan HexNAc4-Hex5-NeuA...

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...

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...

Human skin provides both physical integrity and immunological protection from the external environment, using functionally distinct layers, cell types and extracellular matrix. Despite its central role in human health and disease, the constituent proteins of skin have not been systematically charact...
