General description
Application
Biochem/physiol Actions
Preparation Note
Bei der Beschichtung von Kulturoberflächen sollte Fibronektin in ausgeglichener steriler Kochsalzlösung verdünnt und möglichst dünn aufgetragen werden. Die behandelte Oberfläche sollte dann 45 Minuten bei Raumtemperatur luftgetrocknet werden und ist 2–4 Wochen bei 2–8 °C haltbar.

This is to ask a question regarding coating flasks with the human freeze-dried fibronectin (F1056). After dissolving it in sterile water and diluting to the desired concentration should I incubate the flasks at 4 or 37 degrees overnight? Many thanks!
1 answer-
As noted in the DESCRIPTION section of the Product Detail Page, fibronectin should be diluted in a sterile balanced sterile salt solution and coated with minimal volume. The surface should then be air dried for 45 minutes at room temp and can be stored for 2-4 weeks at 2-8°C. See the information below for a brief protocol:
To coat culture surfaces:
1. Dilute fibronectin in a sterile balanced salt solution
and coat the culture surface (1-5 mg/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.
3. Fibronectin coated cultureware can be stored for
2-4 weeks at 2-8 °C in a closed sterile container or
sterile sealable bags.Helpful?

How do I choose which fibronectin product to use to coat culture surfaces for cell growth?
1 answer-
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 do I determine how much fibronectin is in solution?
1 answer-
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 difference between Fibronectin Products F2006 and F1056?
1 answer-
The difference between Product Nos. F2006 and F1056 is in the purity specifications and endotoxin testing. Product No. 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.

How do I test the wells/flasks that have been coated with fibronectin?
1 answer-
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 solubilized Fibronectin?
1 answer-
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.
