Methods and kits for improving retroviral-mediated gene transfer utilizing molecules, or mixture thereof, containing retroviral binding domains and target cell binding domains

摘要

The present invention provides a kit to carry out retrovirus-mediated gene transfer into target cells. The kit contains a functional material bearing a retrovirus binding domain, another functional material bearing a target cell binding domain, an artificial substrate for incubating the retrovirus contacted with the target cells, and a target cell growth factor for pre-stimulating target cells to spur them along the cell cycle. The kit of the invention may further comprise a recombinant retroviral vector, necessary buffers, and the like.
