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. The FN1 gene mapped to human chromosome 2q35.[1]
FN occurs as a dimeric protein, linked by two disulfide bonds at the end of C-terminal.[2] Within the fibronectin structure, the domains are compactly arranged close to both the amino and carboxyl terminal of the peptide chains.[3] Moreover, it has been observed that despite arising from a single gene up to 20 distinct variants of this gene have been identified in humans.[2]
Application
Fibronectin from human plasma has been used in the determination of H2O2 consumption rate.[4] It has also been used in coating the Sylgard® models for cell culture.[5] It has also been used in cell adhesion and to directly pattern the protein onto the polymeric film.[6][7]
Biochem/physiol Actions
Fibronectin function encompasses a diverse range of biological processes including cell adhesion, growth, migration, wound healing, blood coagulation and metastasis.[1] Fibronectin protein 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. Mutations in FN1 results in glomerulopathy.[8]
Features and Benefits
Adhesive glycoprotein
Derived from human plasma
Recommended surface coverage of 1-5 μg/cm2
Preparation Note
This product is a 0.1% solution of fibronectin. The protein homogeneity is evaluated by immunoelectrophoresis, is endotoxin tested, and the source material was tested negative for HIV, hepatitis B and hepatitis C.
In coating culture surfaces, fibronectin should be diluted in sterile balanced sterile salt solution and coated with minimal volume. Surface should then be air dried for 45 minutes at room temp and can be stored for 2-4 weeks at 2-8°C
Analysis Note
Protein homogeneity is evaluated by immunoelectrophoresis.
