Fibronectin is a large, cell surface and plasma protein that exhibits structural and adhesive properties in cell-associated fibrillar matrices. Fibronectin is one of the primary cell adhesion molecules. Human Plasma Fibronectin is isolated from human plasma by affinity chromtography. Fibronectin has a molecular weight of 440,000 and is made up of two 220,000 dalton polypeptides. Human Fibronectin is filtered (0,2UI) and supplied lyophilized.

Performance and Quality Testing
The purity is determined by SDS-PAGE. Bovine and human fibronectins are assayed for their ability to support cell attachment and spreading, and screened to confirm absence of mycoplasma or bacterial contamination.
