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 thyroid gland shows strong cytoplasmic positivity in glandular cells.
Immunohistochemical staining of human placenta shows strong cytoplasmic positivity in trophoblastic cells.
Summary
Cytoplasmic staining in most tissues at variable intensity. Membranous positivity in a few tissues e.g. gall bladder and epididymis. Blood vessels in brain and a subset of lymphoid cells showed distinct staining.
Moderate to strong cytoplasmic immunoreactivity, often combined with nuclear staining, was observed in most normal tissues. Placenta, esophagus and oral mucosa demonstrated strong cytoplasmic expression. Upper airway epithelia displayed strong cytoplasmic and nuclear staining. Cell membranes were distinctly stained in intestinal glands.
Validation
Two (or more) antibodies yielding partly similar staining patterns which are partly consistent with gene/protein characterization data or consistent with limited gene/protein characterization data
