Description générale
Fibronectin is a class of high-molecular-weight adhesive glycoprotein,[1] predominant in extracellular matrix (ECM) and is widely distributed in tissue and blood. The FN gene, which is highly conserved, gives rise to a minimum of 20 isoforms through alternative splicing in humans. These isoforms include notable variants such as cellular FN and plasma FN.[2] Plasma FN is primarily synthesized in the liver, whereas cellular FN which represents only 5% of the circulating fibronectins[3] is locally produced by various cell types.[2]
Application
Actions biochimiques/physiologiques
Fibronectin plays a major role in biological processes. It interacts with surface receptors and other major ECM proteins like collagen to mediate cellular signals.[2] Fibronectin is involved in a variety of cellular functions, including adhesion, cytoskeletal organization, oncogenic transformation, cell migration, phagocytosis, hemostasis, and embryonic differentiation.[3] This glycoprotein can bind to integrins, collagens, fibrins and glycosaminoglycans (GAGs).[1] FN plays a crucial role in promoting cell cycle progression and proliferation. This interaction influences cyclins and immediate early response genes, contributing to cellular processes related to cell division and growth. FN is also involved in cell survival and protection from apoptosis in various cell types, including epithelial and endothelial cells and leukocytes. FN serves as a critical factor in promoting cell survival and preventing programmed cell death in these cellular contexts.[7] Mutations in the FN gene are associated with FN glomerulopathy and spondylometaphyseal dysplasia.[2] Fibronectin plays a significant role in the wound healing process, and in extracellular matrix (ECM) assembly, hence is considered suitable for tissue engineering applications.[1]
Attention
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.
Notes préparatoires
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.

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 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.
