Generation of lentivirus vectors using recombinant baculoviruses

2008

In spite of advances in conventional four-plasmid transient transfection methods and development of inducible stable production cell lines, production of replication-defective lentiviral vectors in clinical scale has been challenging. Baculovirus technology offers an alternative to scalable virus production as a result of fast and easy production of baculoviruses, efficient transduction of mammalian cells and safety of the baculoviruses. As a first step toward scalable lentiviral production system, we have constructed four recombinant baculoviruses: the BAC-transfer virus expresses green fluorescent protein (GFP) as a transgene and BAC-gag-pol, BAC-vesicular stomatitis virus glycoprotein G …
