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.

Artikel
Fibronectin (FN) plays crucial roles in extracellular matrix fibril assembly and cellular interactions.
The extracellular matrix (ECM) and its attachment factor components are discussed in this article in relation to their function in structural biology and their availability for in vitro applications.
The extracellular matrix (ECM) is secreted by cells and surrounds them in tissues.

How do I determine how much fibronectin is in solution?
1 Antwort-
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.

What is the procedure for coating culture surfaces with fibronectin?
1 Antwort-
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?
1 Antwort-
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 choose which fibronectin product to use to coat culture surfaces for cell growth?
1 Antwort-
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.
