The protein expression bar, with the units none (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 common score is set. For details, see Assays & annotation.
RNA expression shows average values based on RNA-seq data generated by HPA or the Genotype-Tissue Expression (GTEx) consortium.
HPA RNA expression data are reported as number of Fragments Per Kilobase gene model and Million reads (FPKM). For details, see Assays & annotation.
GTEx RNA expression data are reported as reads per kilobase per million mapped reads (RPKM). For details, see Assays & annotation.
The detailed normal tissue page shows images of the stained tissue, together with antibody staining/expression level of the cell types.
If a knowledge-based annotated protein expression is provided, this is reported 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.
