Description

General description

Monoclonal Anti-Cellular Fibronectin (mouse IgM isotype) is derived from the hybridoma produced the fusion of mouse myeloma cells and splenocytes from immunized mice. Fibronectin is an extracellular matrix protein composed of two nearly identical disulfide-bound polypeptides with typical molecular weights of 220-240 kDa. Cellular fibronectin is structurally and antigenically similar to cold insoluble globulin from plasma and polyclonal antibodies to either form usually cross-react. The protein contains several functionally and structurally distinct domains, which may bind to cell surfaces, collagen, heparin, etc.

Specificity

The antibody labels cellular fibronectin in the pericellular matrix of chick embryo and mouse and human fibroblasts grown in tissue culture. It may be used for immunoaffinity purification of cellular fibronectin.

Immunogen

fibronectin antigen released in culture by a human breast cancer cell line

Application

Monoclonal Anti-Fibronectin, Cellular antibody produced in mouse has been used in:
• immunoblot

Biochem/physiol Actions

Fibronectin is a soluble plasma protein that regulates tissue repair and thrombus formation. Insoluble fibronectin is expressed in basement membranes and connective tissue matrix and mainly modulates cell adhesion and migration. Alterations in fibronectin have been associated with microvascular thrombosis, disseminated intravascular coagulation, and atherosclerosis .

Fibronectin may enhance cell adhesion and spreading and affect the routes of cell migration both in vivo and in culture. It has been shown that upon malignant transformation many cells lose their surface bound fibronectin.
