Fibronectin Previously Observed Antibody Staining Patterns
Observed Antibody Staining Data By Tissue Type:
Variations in Fibronectin antibody staining intensity in immunohistochemistry on tissue sections are present across different anatomical locations. An intense signal was observed in cells in the tubules in kidney. More moderate antibody staining intensity was present in cells in the tubules in kidney. Low, but measureable presence of Fibronectin could be seen inadipocytes in breast, cells in the endometrial stroma in endometrium, cells in the molecular layer in cerebellum, cells in the red pulp in spleen, cells in the seminiferous ducts in testis, cells in the white pulp in spleen, glandular cells in the appendix, breast, epididymis, rectum, salivary gland, seminal vesicle, small intestine, stomach and thyroid gland, glial cells in the caudate nucleus, hematopoietic cells in the bone marrow, hepatocytes in liver, macrophages in lung, neuronal cells in the hippocampus, peripheral nerve in mesenchymal tissue, respiratory epithelial cells in the bronchus and nasopharynx, squamous epithelial cells in the esophagus and oral mucosa, trophoblastic cells in the placenta and urothelial cells in the urinary bladder. We were unable to detect Fibronectin 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 Fibronectin expression as measured by anti-Fibronectin 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 Fibronectin. | |
| Epitope of this MAb is located in the 8th type III repeat in the cell-binding region of fibronectin. Fibronectins are disulfide-linked, dimeric glycoproteins of ~440kDa. They possess at least four binding sites for collagen, glycosaminoglycans, transglutaminase,, a cell surface receptor. Fibronectins are involved in cell adhesion, tissue organization,, wound healing. Fibronectins are present in basement membranes, interstitial connective tissue matrix,, blood. Cellular fibronectin is widely distributed in the stroma of many malignant tumors. This MAb is excellent for staining of formalin-fixed, paraffin-embedded tissues. | |
