General description

Fibronectin 1 is a glycoprotein of the extracellular matrix that is coded by FN1 gene. It is expressed in the plasma and at the cell surface. FN1 is mapped to human chromosome 2q35. Proteolytic fragments of fibronectin has a cell binding domain.

Application

Fibronectin Proteolytic Fragment from human plasma has been used in pre adsorbed antibody blocking assay and EC-pericyte tube coassembly.

Biochem/physiol Actions

Fibronectin participates in cell adhesion, growth, migration, wound healing, blood coagulation and metastasis. Mutations in FN1 results in glomerulopathy. It plays an important role in cell attachment and spreading, control of cell cytoskeleton, morphology and differentiation. FN1 is also involved in extracellular matrix formation, hemostasis and thrombosis. Proteolytic fragments of fibronectin plays a vital role in mononuclear phagocyte function.

Caution

The product should be stored at -20°C.

Preparation Note

This product is lyophilized from phosphate buffered saline with sucrose as a cryoprotectant. The source material has tested negative for antibody to HIV, HCN, and HBsAg. It is soluble in water at 0.5 mg/mL and yields a clear to slightly hazy solution.
