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 kidney shows distinct extracellular positivity.
Immunohistochemical staining of human vulva/anal skin shows distinct positivity in plasma.
Summary
Weak to moderate cytoplasmic positivity was seen in most normal tissues. Distinct extracellular staining was observed in most tissues. Glandular cells of salivary gland and Purkinje cells displayed strong positivity.
Most normal tissues displayed weak cytoplasmic staining or were negative. Strong staining was observed in breast glands and Leydig cells in testis while moderate cytoplasmic immunoreactivity was observed in renal tubules and Purkinje cells. Plasma was distinctly stained.
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
Two (or more) antibodies yielding similar staining patterns which are consistent with available gene/protein characterization data
