Bovine Fibronectin Protein, CF

(6 citations)   
  • Purity
    >90%, by SDS-PAGE under reducing conditions and visualized by silver stain
  • Endotoxin Level
    <1.0 EU per 1 μg of the protein by the LAL method.
  • Activity
    Measured by its ability to support cell attachment and spreading when used as a substratum for cell culture. In this application, the recommended concentration for this effect is
    1‑5 µg/cm2.  Fibronectin can also be added in the media to support cell spreading at a concentration of 0.5-50 µg/mL.
    Optimal concentration depends on cell type as well as the application or research objectives.
  • Source
    Bovine plasma-derived
Formulation Supplied as a 0.2 μm filtered solution in Tris-HCl, NaCl and Urea.

Background: Fibronectin

Fibronectin is an extracellular matrix (ECM) component and is one of the primary cell adhesion molecules (1). It is composed of multiple homologous repeats and contains many functional domains. The occurrence of different isoforms is due to alternative mRNA splicing of the ED-A, ED-B and III-CS regions and subsequent post-translational modification. Although non-reactive with adhesion receptors in its soluble state, Fibronectin is highly adhesive when on the surface (2). Polymerization of Fibronectin into ECM must be tightly regulated to ensure appropriate adhesive proporties upon ECM formation. Because of its ability to interact with many ligands (e.g. cells, heparin, fibrin, collagen, DNA, immunoglobulin), Fibronectin plays an important role in normal morphogenesis, including cell adhesion, migration, differentiation, and specific gene expression (3 - 6).
