  • Patent number: 6258595
    Abstract: A method for producing recombinant adeno-associated virus in the absence of contaminating helper virus or wild-type virus involves culturing a mammalian host cell containing an rAd/AAV hybrid virus, an AAV rep sequence and an AAV cap sequence under the control of regulatory sequences directing expression thereof. The rAd/AAV hybrid virus contains a rAAV construct to be packaged into an AAV virion in a backbone containing the adenoviral sequences necessary to express E1a and E1b gene products and to permit replication of the hybrid virus. The method of the invention permits replication of the hybrid virus and production of rAAV virion in this host cell in the absence of a helper virus and obviates a subsequent purification step to purify rAAV from contaminating virus.

  • Patent number: 5756283
    Abstract: A method for enhancing the efficiency of transduction of a recombinant AAV into a target cell is provided. The target cell is infected with a recombinant adeno-associated virus comprising a selected transgene under the control of regulatory sequences. The infected cell is contacted with an agent which facilitates the conversion of single stranded recombinant virus to its double stranded form. When this conversion occurs in the target cell, enhanced transduction of the recombinant virus into said target cell results. The agent can be a helper virus providing a gene which facilitates the conversion, or an agent to which the infected cell is exposed, which facilitates the conversion. In a similar manner, a novel recombinant AAV is provided which contains the facilitating gene and the transgene. The methods may be performed ex vivo or in vivo.
