Description

Caution

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.

Frequently Asked Questions

Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
How do I choose which fibronectin product to use to coat culture surfaces for cell growth?
The species source for the fibronectin used when coating culture surfaces is not important.It is the presence of the RGD binding site that is present in all fibronectins that promotes binding.
How long can I store the fibronectin solution?
The product is good for at least a year at 2-8 °C if kept sterile.
How long can I store fibronectin coated plates, etc?
Fibronectin coated cultureware can be stored for 2-4 weeks at 2-8 °C in a closed sterile container, or in sterile sealable bags.
What is the procedure for coating culture surfaces with fibronectin?
To coat culture surfaces: 1. Dilute fibronectin in sterile balanced salt solution and coat the culture surface (1-5 μg/cm2) with a minimal volume.2. Allow to air dry for at least 45 minutes at room temperature.Excess fibronectin may be removed by aspiration, but this is not necessary.
How do I solubilized Fibronectin?
Dissolve at 1 mg/mL in water. Allow to dissolve for at least 30 minutes at 37 °C. A small amount of undissolved material may remain. This will not affect product performance.
How do I test the wells/flasks that have been coated with fibronectin?
We test the coated culture surface by culturing cells.We compare the adherence of the cells to wells that have been coated with media containing BSA (negative) and media containing 10% FBS (positive).The cell growth should be not less than 50% of the positive control and greater than 50% of the negative control.
How do I determine how much fibronectin is in solution?
As the product may contain undissolved material, the amount of fibronectin in solution can be determined by UV absorbance.The extinction coefficient for a 1% solution (10 mg/ml) is 13.5 at 280 nm.
How do I find price and availability?
There are several ways to find pricing and availability for our products.Once you log onto our website, you will find the price and availability displayed on the product detail page.You can contact any of our Customer Sales and Service offices to receive a quote.

What is the Department of Transportation shipping information for this product?
Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product.
What is the difference between Fibronectin Products F2006 and F1056?
The difference between Product Nos. F2006 and F1056 is in the purity specifications and endotoxin testing.ProductNo. F2006 has a purity specification of ≥90% and is not tested for endotoxin contamination.Product No. F1056 has a purity specification of≥95% and is tested for endotoxin contamination with a specification of ≤100 EU/mg.
