Can the MISSION lentiviral particles be further propagated in the lab?
No, the viral particles cannot be propagated for biosafety reasons. The MISSION TRC lentiviral particles are replication incompetent. The particles are made using features of 2nd and 3rd generation lentiviral packaging systems. Genes for replication and structural proteins are absent in the packaged viral genome since these genes are supplied by other plasmids in the packaging cells. The viral genome contains only the region between the 5’ and 3’ LTRs of pLKO.1. In addition, the lentiviral vector contains a self-inactivating 3’ LTR that renders it unable to produce infectious virus once it integrates into the host chromosome.
