Digital spatial profiling (DSP) is an emerging powerful technology for proteomics and transcriptomics analyses in a spatially resolved manner for formalin-fixed paraffin-embedded (FFPE) samples developed by nanoString Technologies.

New Advances in Single-Cell and Spatial Genomics (2020) Simultaneous Proteomics and Transcriptomics

Spatial or organelle proteomics is the systematic study of the proteins and their sub-cellular localization; these compartments can be organelles, i.e. structures defined by lipid bi-layers, macro-molecular assemblies of proteins and nucleic acids or large protein complexes. Highly resolved spatial proteomics has the potential to define the complex cellular and molecular architecture of the human brain in health and disease. (16,17) Most of our approximately 20 000 genes are expressed in the brain in a temporospatial manner, and many demonstrate alternative splicing in different brain regions, hinting at the existence of a very complex, highly compartmentalized Spatial proteomics is the systematic study of protein sub-cellular localisation. In this workflow, we describe the analysis of a typical quantitative mass spectrometry-based spatial proteomics experiment using the MSnbase and pRoloc Bioconductor package suite. Spatial (or organelle) proteomics is the study of the localisation of proteins inside cells.

Spatial proteomics

We quantify 10,701 proteins as a function of their spatial location and cellular origin. Significant advances in mass spectrometry technologies and proteomic workflows now make proteomics notably more accessible for plant science. This PCA workshop aims to bring together world leaders in spatial and quantitative proteomics from plant sciences and beyond to help realize the development of a comprehensive PCA proteome. Spatial proteomics is the systematic and high-throughput study of protein sub-cellular localisation. A wide range of techniques (reviewed in [ 10, 26 ]) and computational methods [11a] have been documented, that confidently infer the localisation of thousands of proteins.

Here we describe a systematic mass spectrometry‐based method for spatial proteomics. The approach uses simple fractionation profiling and has two applications: Firstly it can be used to infer subcellular protein localization on a proteome‐wide scale, resulting in a protein map of the cell.

Introduction. Exploring protein annotations and defining sub-cellular localisation markers (i.e. known residents of a specific sub-cellular niche in a species, under a condition of interest) play important roles in the analysis of spatial proteomics data.
