Cell Genesys obtains United States patent.

Cell Genesys, Inc. (Foster City, CA) and Whitehead Institute for Biomedical Research (Cambridge, MA) have patented retroviral vectors which include an insertion site for genes of interest and are capable of expressing high levels of the protein derived from the genes of interest in a wide variety of transfected cell types. Also disclosed are retroviral vectors lacking a selectable marker, thus rendering them suitable for human gene therapy in the treatment of a variety of disease states without the co-expression of a marker product, such as an antibiotic. These retroviral vectors are especially suited for use in certain packaging cell lines. (US 6,544,771)
