Fibronectin Rat
Plasma fibronectin level is elevated in severe coronary artery disease. Increased plasma fibronectin levels are related with venous thromboembolism (VTE) particularly in males, and extend the probable association between biomarkers and risk factors for arterial atherothrombosis and VTE. Fibronectin plays a role in several cellular processes, including tissue repair, embryogenesis, blood clotting, and cell migration/adhesion. Fibronectin consists in two main forms: 1) as an insoluble glycoprotein dimer that serves as a linker in the etracellular matrix and 2) as a soluble disulphide linked dimer found in the plasma. The plasma form is produced by hepatocytes, and the ECM form is synthesized by fibroblasts, chondrocytes, endothelial cells, macrophages, as well as certain epithelial cells. Fibronectin alos takes part as a general cell adhesion molecule by anchoring cells to collagen or proteoglycan substrates. Fibronectin organizes cellular interaction with the ECM by binding to different components of the extracellular matrix and to membrane-bound Fibronectin receptors on cell surfaces. Molecular Weight 220kDa.
Accession Number
Formulation
The Rat Fibronectin was lyophilized from a concentrated 1mg/ml solution containing 20mM Tris Cl pH-7.5.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Purity
Greater than 95.0% as determined by SDS-PAGE.
Solubility
Purified Rat fibronectin has a tendency to form insoluble aggregates upon reconstitution. We suggest reconstituting the 1mg Fibronectin with a chaotropic agent such as urea at room temperature at a concentration of 0.2mg/ml using sterile water.
Let stand 1-2 hours.

Stability
Store the lyophilized fibronectin at 4oC. Upon reconstitution fibronectin should be stored at 4oC for 2 weeks and for future use below -18oC.
Please prevent freeze-thaw cycles.
