General Description

Monoclonal Anti-Fibronectin (mouse IgG1 isotype) is derived from the hybridoma produced the fusion of mouse myeloma cells and splenocytes from immunized mice. Fibronectin (FN) belongs to glycoprotein family widely expressed in many tissues. FN is an extracellular matrix protein composed of two nearly-identical disulfide-bound polypeptides with typical molecular weights of 220-240 kDa. There are three isoforms of fibronectin, that includes cellular FN, plasma FN and fetal FN. 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 gene in human chromosome is mapped to 2q35.

Biochem/physiol Actions

Fibronectin (FN) 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. FN is upregulated in many cancers. FN increases the expression of matrix metalloproteinases (MMPs), promoting cancer cell invasion and metastasis.
