Abstract
Lentiviral vectors modified at the 5′ LTR or both the 5′ and 3′ LTR's are useful in the production of recombinant lentivirus vectors. Such vectors can be produced in the absence of a functional tat gene. Multiple transformation of the host cell with the vector carrying the transgene enhances virus production.
Claims17
A lentiviral packaging system comprising a structural lentiviral vector system comprising a first lentiviral vector that encodes a structural gag gene, and a second lentiviral vector that encodes a structural pol gene, wherein the lentiviral packaging system lacks a functional tat gene.
