Background

Recombinant Human Fibronectin (FN) Protein , including three functional regions (cell binding domain, heparin binding domain, and CS1 site), can significantly enhance retrovirus mediated gene transfer to mammalian cells. This effect may be due to colocalization of retroviral particles and target cells on rhFN CH-296 chimeric molecule via retroviral particles or heparin binding region II binding to cell adhesion sites VLA-4 and/or VLA-5. According to the research results of Hannenberg et al., there is typically 50% to 75% gene transduction of cells with the coating method.
