Specificity Comments: Fibronectins are disulfide-linked, dimeric glycoproteins of ~440kDa. They possess at least four binding sites for collagen, glycosaminoglycans, transglutaminase, and a cell surface receptor. Epitope of this MAb is located in the 2nd-3rd type-III repeats of fibronectin. Fibronectins are extracellular matrix glycoproteins that are essential for embryonic development. Fibronectins are also involved in cell adhesion, tissue organization, and wound healing. Fibronectins are present in basement membranes, interstitial connective tissue matrix, and blood. Cellular fibronectin is widely distributed in the stroma of many malignant tumors. This MAb reacts with human cellular fibronectin, but not plasma fibronectin.
Fibronectin is a disulfide-bonded dimer with a molecular weight range of 230-250 kDa. In the extracellular matrix of several connective tissues and vessels, fibronectin is present as an insoluble protein that is extensively cross-linked by interchain disulfide bonds forming high molecular mass polymers. Fibronectin is most abundant during embryonic development and tissue remodeling. Fibronectin is also present at high concentrations as a soluble plasma protein. Fibronectin is organized as a linear series of repeating modules which form domains for interaction with fibronectin itself, other matrix components (e.g. collagen and heparin) and receptors on cells (e.g. integrins). Fibronectin is present in a soluble dimeric form in plasma, and in a dimeric or multimeric form at the cell surface and in extracellular matrix. Fibronectin is involved in cell adhesion and migration processes including embryogenesis, wound healing, blood coagulation, host defense, and metastasis. Fibronectin has been implicated in carcinoma development in lung cancer. Further, Fibronectin expression is increased especially in non-small cell lung carcinoma. The adhesion of lung carcinoma cells to Fibronectin enhances tumorgenecity and confers resistance to apoptosis induced by standard chemotherapeutic agents. The gene encoding Fibronectin has three regions subject to alternative splicing, with the potential to produce 20 different transcript variants. However, the full-length nature of some Fibronectin variants has not been determined.
