  • STABLE LENTIVIRUS PACKAGING CELL LINE AND PREPARATION METHOD THEREFOR
    Publication number: 20240124848
    Abstract: Provided are a stable lentivirus packaging cell line and a preparation method therefor. The stable lentivirus packaging cell line contains a packaging plasmid group consisting of a pPuro.coTetR plasmid, a pVSVG plasmid, and a pGagPol-RRE-NES-cINT plasmid, wherein the pPuro.coTetR plasmid contains a CoTetR gene, the pVSVG plasnid contains a VSVG gene, and the pGagPol-RRE-NES-cINT plasmid contains GagPol and Rev genes. The stable lentivirus packaging cell line is relatively stable in terms of passage, virus production, and a genetic gene copy number, and the lentivirus produced by using the stable lentivirus packaging cell line has a high titer and a low impurity content.
