fibronectin from human plasma

General description

Fibronectin (FN) is an extracellular matrix protein composed of two nearly-identical disulfide-bound polypeptides with typical molecular weights of 220-280 kDa. Cellular fibronectin is structurally and antigenically similar to cold insoluble globulin from plasma and antibodies to either form usually cross-react. Careful analysis of the FN molecule indicates that it contains several functionally and structurally distinct domains which may bind to cell surfaces and to a variety of molecules such as collagen, heparin, gelatin, fibrin and DNA. FN’s play an important role in diverse biological phenomena including cell adhesion, cell migration, hemostasis and thrombosis, wound healing and the ability to induce a more normal phenotype in transformed cells.

Mouse monoclonal clone FN-15 anti-Fibronectin antibody labels fibronectin in the pericellular extracellular matrix of cultured human fibroblasts using indirect immunofluorescent methods. It also labels fibronectin in chicken and mouse cells. The FN-15 antibody specifically stains fibronectin in immunoblotting, and in an ELISA is reactive with human plasma fibronectin.


Mouse monoclonal clone FN-15 anti-Fibronectin antibody may be used to specifically localize fibronectin in human cell culture and in tissue sections by immunoblotting and immunohistochemical techniques. Monoclonal antibodies reacting specifically with FN may be used to localize FN in human cell cultures, in tissue sections and in plasma.
