On the top, protein expression in current human tissue, based on all annotated cell types, is reported with the units not detected (n), low (l), medium (m) and high (h). Underneath, protein expression in each annotated cell type are reported using the same units.
Protein expression data is based on knowledge-based annotation. For genes where more than one antibody has been used, a collective score is set.
If knowledge-based annotation could not be performed for a gene, no data is displayed here. View antibody staining data further down this page.
A summary of mRNA expression data available for current tissue based on several datasets. The mRNA expression levels in human tissues are based on RNA-seq data generated by the Human Protein Atlas (HPA), Genotype-Tissue Expression (GTEx) portal and CAGE data generated by the FANTOM5 consortium. Consensus normalized expression levels for human tissues was created by combining the data from HPA and GTEx datasets.
The mRNA expression levels in pig are based on RNA-seq data generated by the Human Protein Atlas (HPA), and for mouse, HPA data and in situ hybridization generated by the Allen brain atlas are reported.

The detailed normal tissue page shows images of the stained tissue, together with antibody staining and expression level of the cell types. A knowledge-based annotated protein expression is provided for each cell type at the top of the page and the staining level of the individual antibodies is given underneath each antibody ID.
Samples from up to three different individuals have been stained for each antibody. The gender, age and tissue characterization are reported for each individual (patient) and are viewable when clicking on the image for magnification.
The images can be clicked for an enlarged view that can be panned. From the enlarged view, all stained images for all antibodies can be browsed (represented by miniature images). The miniature image with an orange overlay is the currently displayed image.
For selected proteins extended tissue profiling is performed in addition to standard tissue microarrays. The section below contains results from the extended profiling.

Lactating glandular cells
BREAST - HPA RNA-seqi
The RNA-seq details section shows detailed information about the individual samples used for the transcript profiling and results of the RNA-seq analysis.
Information about each individual sample is listed below, including gender, age, a tissue section image and estimated fractions of cell types. nTPM (normalized transcripts per million) values give a quantification of the gene abundance which is comparable between different genes and samples.
Glandular cells: 15 Adipocytes: 5 Other cell types: 80
Female, age 80
Sample 2 TPM: 0.7
Glandular cells: 5 Adipocytes: 15 Other cell types: 80
Female, age 47
Sample 3 TPM: 7.9
Glandular cells: 5 Adipocytes: 5 Other cell types: 90
Female, age 38
Sample 4 TPM: 183.3
Glandular cells: 40 Adipocytes: 5 Other cell types: 55
BREAST - GTEx RNA-seqi
RNA-Seq data generated by the Genotype-Tissue Expression (GTEx) project from human tissues is reported as mean nTPM. More information can be found on the GTEx portal.
Distribution across the dataset is visualized with box plots, shown as median and 25th and 75th percentiles. Points are displayed as outliers if they are above or below 1.5 times the interquartile range. nTPM values of the individual samples are presented next to the box plot.
