The human protein atlas is a unique undertaking to profile the protein abundance in tissues and cells using antibody-based proteomics techniques. It contains information for a large majority of all human protein-coding genes regarding the expression and localization of the corresponding proteins based on both RNA and protein data. The tissue atlas contains information of 44 different human tissues and organs with annotation data for altogether 83 different cell types. The transcriptomics data provide quantitative data on gene expression levels across the tissues and organs, while the antibody-based protein profiles show the spatial distribution at a single cell level for the corresponding protein in the various substructures and cell types of the tissues. In SlideBase, we present the possibility to select genes based on gene expression or protein abundance, or a combination of the two.
