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. Bovine Plasma Fibronectin is purified from plasma by affinity chromatography on gelatin-Sepharose and further purified by ion exchange chromatography to remove glycosaminoglycans. Bovine Fibronectin is filtered (0,2 μm) and supplied lyophilized.
