The Human Protein Atlas portal is a publicly available database with
millions of high-resolution images showing the spatial distribution of
proteins in 44 different normal human tissues and 20 different cancer
types, as well as 46 different human cell lines. The data is released
together with application-specific validation performed for each
antibody, including immunohistochemisty, Western blot analysis and, for a
large fraction, a protein array assay and immunofluorescent based
confocal microscopy. The database has been developed in a gene-centric
manner with the inclusion of all human genes predicted from genome
efforts. Search functionalities allow for complex queries regarding protein expression profiles, protein classes and chromosome location.
