General description
Two types of Fibronectin are present in vertebrates: soluble plasma Fibronectin and insoluble cellular Fibronectin. The plasma form of Fibronectin (formerly known as cold-insoluble globulin or CIG) is synthesized by hepatocytes, secreted to blood and upon tissue injury, is incorporated into fibrin clots effecting platelet function and mediating hemostasis.8 Cellular Fibronectin is synthesized by many cell types, including fibroblasts, endothelial cells, chondrocytes, synovial cells and myocytes. It is assembled by cells as they migrate into the clot to reconstitute damaged tissue.
Specificity
Monoclonal Anti-Fibronectin antibody specifically recognizes epitope located within the fourth type-three repeat of human plasma fibronectin. The antibody localizes plasma and cellular fibronectin both in its natural and denatured-reduced forms. The product reacts with fibronectin from human, goat, bovine4, porcine5, mouse6, rat7, dog and chicken origin.
Application
The antibody may be used in various immunochemical techniques including Immunoblotting1, ELISA, RIA1-2, Immunofluorescence3 and Immunohistochemistry4.
Biochem/physiol Actions
Fibronectin (FN) is a multi-domain glycoprotein composed of two nearly identical disulfide-bound polypeptides with molecular weights of 220-240 KDa. It is a ubiquitous and essential component of the extracellular matrix (ECM) which plays a vital role during tissue repair. Fibronectin functions both as a regulator of cellular processes and as an important scaffolding protein to maintain and direct tissue organization and ECM composition. It is widely expressed by multiple cell types and is critically important in vertebrate development, as demonstrated by the early embryonic lethality of mice with targeted inactivation of the FN gene. Fibronectin is suggested to enhance cell adhesion and spreading and to affect the routes of cell migration both in vivo and in culture.11 It has been shown that upon malignant transformation many cells lose their surface bound fibronectin.
Physical form
Supplied as a solution in 0.01 M phosphate buffered saline pH 7.4, containing 15 mM sodium azide as a preservative.
Storage and Stability
For continuous use, store at 2-8°C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.

The extracellular matrix provides a framework for cell adhesion, supports cell movement, and serves to compartmentalize tissues into functional units. Fibronectin is a core component of many extracellular matrices where it regulates a variety of cell activities through direct interactions

Fibronectin plays a major role in the adhesion of many cell types. The extent of cell adhesion in vitro is related not only to the ability of the cells to interact with matrix-bound fibronectin, when it is present, but also

To examine the role of fibronectin in vivo, we have generated mice in which the fibronectin gene is inactivated. Heterozygotes have one half normal levels of plasma fibronectin, yet appear normal. When homozygous, the mutant allele causes early embryonic lethality
