Fibronectin

Fibronectin is a high-molecular weight (~440kDa) glycoprotein of the extracellular matrix that binds to membrane-spanning receptor proteins called integrins. Similar to integrins, fibronectin binds extracellular matrix components such as collagen, fibrin, and heparan sulfate proteoglycans (e.g. syndecans).

Fibronectin ELISA Kit
A high sensitive complete sandwich ELISA for the selective determination of intact uncleaved fibronectin in human plasma. The Fibronectin ELISA Kit is based on two  monoclonal antibodies. One monoclonal antibody is immobilized to microtitre plates for use as a catching antibody; the second peroxidase-labeled monoclonal antibody recognizes exclusively uncleaved fibronectin.
