Calgranulin B Previously Observed Antibody Staining Patterns
Observed Subcellular, Organelle Specific Staining Data:
Anti-S100A9 antibody staining is expected to be primarily localized to the cell junctions and cytosol.
Observed Antibody Staining Data By Tissue Type:
Variations in Calgranulin B antibody staining intensity in immunohistochemistry on tissue sections are present across different anatomical locations. An intense signal was observed in hematopoietic cells in the bone marrow, squamous epithelial cells in the cervix, uterine, esophagus and oral mucosa, epidermal cells in the skin, cells in the red pulp in spleen and squamous epithelial cells in the tonsil and vagina. More moderate antibody staining intensity was present in hematopoietic cells in the bone marrow, squamous epithelial cells in the cervix, uterine, esophagus and oral mucosa, epidermal cells in the skin, cells in the red pulp in spleen and squamous epithelial cells in the tonsil and vagina. Low, but measureable presence of Calgranulin B could be seen in cells in the white pulp in spleen. We were unable to detect Calgranulin B in other tissues. Disease states, inflammation, and other physiological changes can have a substantial impact on antibody staining patterns. These measurements were all taken in tissues deemed normal or from patients without known disease.
Observed Antibody Staining Data By Tissue Disease Status:
Tissues from cancer patients, for instance, have their own distinct pattern of Calgranulin B expression as measured by anti-Calgranulin B antibody immunohistochemical staining. The average level of expression by tumor is summarized in the table below. The variability row represents patient to patient variability in IHC staining.

| General Description of Calgranulin B. | |
| Recognizes a 12-14kDa doublet of Calgranulin A/B (also known as S100A8/A9 or MRP-8/14); expressed by granulocytes, monocytes, by tissue macrophages.The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm,/or nucleus of a wide range of cells,, involved in the regulation of a number of cellular processes such as cell cycle progression, differentiation. Altered expression of this protein is associated with the disease cystic fibrosis. This MAb reacts with neutrophils, monocytes, macrophages,, squamous mucosal epithelia, has been shown as an important marker for identifying macrophages in tissue sections. | |
