The normal tissue atlas contains information regarding the expression profiles of human genes both on the mRNA and protein level. The protein expression data is derived from antibody-based protein profiling using immunohistochemistry.
Altogether 83 different cell types, corresponding to 44 normal human tissues, have been analyzed and the data is presented as pathology-based annotation of expression levels. All underlying images of immunohistochemistry stained normal tissues are displayed in the normal tissue atlas.
The mRNA expression data is derived from deep sequencing of RNA (RNA-Seq) from 32 major different normal tissue types. The protein data covers 16613 genes (82%) for which there are available antibodies.
