Isolated recombinant polynucleotides comprising elements which promote encapsidation into AAV particles, packaging cells comprising the recombinant polynucleotides, and methods for their use are provided in the present invention. These isolated recombinant polynucleotides comprise a non-AAV ITR encapsidation element (such as the P1 sequence located within the AAV S1 integration site of human chromosome 19) operably linked to one or more heterologous genes to be encapsidated. The constructs may be either integrated into a mammalian cell genome, maintained episomally, or provided transiently.

Methods, compositions, and cells for encapsidating recombinant vectors in AAV particles

High-efficiency AAV packaging constructs and methods for their use are provided. in the present invention. These high-efficiency packaging constructs comprise an activating element (such as the P1 sequence located within the AAV S1 integration site of human chromosome 19) amplifiably linked to one or more AAV packaging genes. The constructs may be either integrated into a mammalian cell genome or maintained episomally. Use of the high-efficiency AAV packaging vectors of the invention provides for controlled amplifiable production of rAAV vector constructs.
