The protein expression bar, with the units not detected (n), low (l), medium (m) and high (h), is based on a best estimate of the true protein expression for proteins where the antibody staining pattern has been analyzed by knowledge-based annotation. For genes where more than one antibody has been used, a collective score is set. For details, see Assays & annotation.
RNA expression shows average values based on RNA-seq data generated by HPA, the Genotype-Tissue Expression (GTEx) consortium or the FANTOM5 consortium.
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. TPM (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: 7000.4
Glandular cells: 5 Adipocytes: 15 Other cell types: 80
Female, age 47
Sample 3 TPM: 5336
Glandular cells: 5 Adipocytes: 5 Other cell types: 90
Female, age 38
Sample 4 TPM: 404.2
Glandular cells: 40 Adipocytes: 5 Other cell types: 55
BREAST - GTEx RNA-seqi
RNA-Seq data is reported as average RPKM (reads per kilobase per million mapped reads), generated by the Genotype-Tissue Expression (GTEx) project. More information can be found on the GTEx portal.
Normal 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. RPKM values of the individual samples are presented next to the box plot.
