The normal tissue page shows antibody staining and, when available, knowledge-based annotated protein expression in 46 human tissues. The assay and annotation is described here.
This page starts with a summary. The summary data can be based on one or more antibodies (reported by the "Antibodies in assay"-field). If the data is based on one single antibody, the IH validation score for that antibody is reported in the "Reliability (Single)"-field (color-coding described here). If the data is based on more than one antibody, the reliability score for the data is reported as "Reliability (APE)" (color-coding described here).
The tissues and cell types can be ordered by organ, cell type or alphabetically.
For each tissue and cell type, the antibody staining is given with the yellow-scale color-coding (described by the scale in the box to the right). Each available antibody is listed in a separate column and the antibody identifier is available at the bottom of the tissue list. The images and annotations can be accessed by clicking on the tissue name.
When available, a knowledge-based annotated protein expression (APE) is given to the right of the antibody staining values. The level of expression is given by a blue-scale color-coding (described by the scale in the box to the right).
At the very bottom of this page, a summary of the staining from each antibody is given, together with a representative image and the immunohistochemistry validation score for the antibody.
Immunohistochemical staining of human breast shows moderate cytoplasmic positivity in glandular cells.
Immunohistochemical staining of human kidney shows strong cytoplasmic and membranous positivity in cells in tubules.
Summary
Normal tissues displayed weak to moderate cytoplasmic positivity with additional membranous staining in a few tissues. Lymphoid tissues, glial cells, endometrial stromal cells, skeletal and smooth muscle cells were weakly stained or negative.
Squamous epithelium, duodenum, islets of Langerhans, parathyroid gland, urothelial cells, cells in seminiferus ducts, cardiac myocytes and epididymis showed moderate cytoplasmic and often membranous positivity. A subset of cells in renal tubules and squamous epithelium of esophagus showed strong positivity. Remaining normal tissues were weakly stained or negative.
Validation
Two (or more) antibodies yielding dissimilar or partly similar staining patterns and there is no available gene/protein characterization data or only limited gene/protein characterization data
