Fibronectin is an adhesive glycoproteins found in both the cell surface and in plasma.


Fibronectin from human plasma can be used with epithelial cells, mesenchymal cells, neuronal cells, fibroblasts, neural crest cells, and endothelial cells. It is recommended for use as a cell culture substratum at 1-5 μg/cm2 or 0.5-50 μg/mL. The optimal concentration does depend on cell type as well as the application and research objectives.

Fibronectin from human plasma is used for the following applications:
• Used in cell seeding and neuronal differentiation (as one of the components in expansion medium for the re-suspension of CBSCs (Cord blood stem cells) and is also used in differentiation medium)1
• Used in cell culture (the culture chamber was coated with fibronectin for the expression of HEK293 cells)2
• Used in murine embroyonic stem cell line (CCE) culture and induction of endothelial cell differentiation (for the induction of endothelial cell differentiation, cultured cells were pre-coated with fibronectin)3
• In-vitro fibronectin (FN) pulldown assays4
• Protein specificity5
• Immunofluorescence (used in staining of cell layers for membrane type-1 matrix metalloproteinase (MT1-MMP) for coating of slides)6
• Extracellular matrix binding assay7
• Used in cell migration study8


The reconstituted solution should be stored in working aliquots at -20°C or lower. Vortexing, excessive agitation, or additoinal freezing and thawing of reconstituted fibronectin are not recommended.

Preparation Note

This product is lyophilized from 0.05 M Tris buffered saline at pH 7.5. It is soluble at 1 mg/mL in water, and should be allowed to dissolve for at least 30 minutes at 37°C. A small amount of undissolved material may remain, but it will not affect performance. 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.
