A novel package system based on an EBV replicon vector for producing high titer recombinant adeno-associated virus vector

ADENO-ASSOCIATED virus (AAV) was a human parvovirus considered as a gene delivery vehiclefor human gene therapy. Recombinant AAV vector (rAAV) could mediate the foreign DNAintegration into chromosome and establish a stable expression in the infected cells. As a viraltransduction vector, rAAV was superior to the traditional retrovirus vector for its high safety.no pathogenicity, and capacity of infecting postmitosis cells. The current strategy for produc-
