Product Description
Fibronectin is a widely used broad range natural cell attachment factor. This product has been purified from human plasma where it is found as a dimer and has a size of 440-500 kDa with two similar subunits (220-250 kDa ) linked by two disulfide bonds.
Fibronectin’s primary function is related to cell adhesion and attachment to extracellular matrix. Certain domains of Fibronectin have been found to play important roles that involve interactions with collagen, heparin and other cell surface glycosaminoglycans (GAGs).
Fibronectin is ideal for coating of surfaces and is typically used at a concentration of 1-5 µg/cm2 . It is provided in user-friendly packaging for use and storage. Fibronectin is sterile filtered and is supplied as a sterile, lyophilized product.

Coating Procedure:
Use these recommendations as guidelines todetermine the optimal coating conditions for yourculture system.
- Add 5 ml of sterile water to yield aconcentration of 1 mg/ml.
- Incubate for 30-60 minutes at 37°C to dissolve.Do not agitate.Note: Upon reconstitution, the solution maycontain a small amount of insoluble aggregatedmaterial. This phenomenon is inherent tofibronectin and does not affect productperformance.
- Further dilute the 1 mg/ml solution with PBS orcell culture medium to achieve desired workingconcentration.
- For coating of cell culture plasticware,5 µg/cm2is typical.
- Incubate for approximately 45 minutes at 15 to25°C.
- Aspirate remaining material being careful to nottouch the coated surface.
- It is possible, but not necessary, to rinse thecoated surface with PBS or medium.
- Plates are ready for use. The coated culturevessels should be used immediately and shouldnot be allowed to dry.
Product Q & A
440 kDa. The protein is a dimer of two 220 kDa identical subunits. It shows up as 220 kDa on a reduced gel, and 440 kDa on a non-reduced gel.
