Discription：Fibronectin （FN） is a large, modular glycoprotein that generates a polymeric fibrillar network in the extracellular matrix （ECM） , and forms soluble, disulfide-linked dimeric protomers in plasma and other body fluids. Fibronectin is a ligand for many molecules, including fibrin, heparin, chondroitin sulfate, collagen/gelatin, and integrin. It is involved in multiple cellular processes such as cell adhesion/migration, blood clotting, morphogenesis, tissue repair, and cell signaling.Recombinant Human Fibronectin fragment is a recombinant fibronectin fragment composed of three functional domains： the cell-binding domain （C-domain） , heparin-binding domain （H-domain） , and CS-1 sequence. The fragment can improve the efficiency of retroviral-mediated gene transduction by helping the co-localization of target cells and virions
