RECOMBINANT HUMAN HERPES SIMPLEX VIRUS FOR PRODUCING LENTIVIRUS VECTORS

摘要

The present invention describes one kind of recombinant human herpes simplex virus-1, named HSV1-Lenti-helper virus, and its genome has inserted various trans protein expressing cassettes, such as gag, pol, VSV-G, Rev, etc. needed for packing slow virus carrier. Infecting carrier cell strain with the recombinant HSV virus can express gag, pol, VSV-G, Rev and other protein in high level, and this can save slow virus carrier genome existing in provirus form in the carrier cell strain chromosome to pack slow virus carrier. By means of affinity chromatography, ion adsorption chromatography, hyperfiltration separation or other method, the slow virus carrier may be separated from HSV to reach the aim of purification. The method features the virus infection mode, rather than plasmid transfection mode, in producing slow virus carrier with high carrier titer, low cost and adaptability for large-scale production.
