|Stable Virus Packaging Cell Lines (SJ-95-0005)|
|Description||One of the major limitations of human gene therapy vectors has been the low rate of infectivity due to the relatively low expression of membrane proteins that serve as the viral receptor. This invention describes the construction of a stable virus packaging cell line which utilizes the VSV-G (vesicular stomatitis virus) membrane protein as the viral receptor, which has a much broader host range than vectors currently in use in gene therapy trials. Vector particles can also be concentrated to high titers. This packaging cell line could be developed by a pharmaceutical company or clinical grade reagent supplier to produce high titer viral particles with a broad host range whichexpress a particular gene of interest for use as agene therapy treatment.|
|Keywords||Gene therapy, packaging cell line, VSV (vesicular stomatitis virus)|
