  • Patent number: 8524446
    Abstract: A method for detecting and isolating AAV sequences in a sample of DNA obtained from tissue or cells is provided, which sample contains DNA and proviral AAV. The method involves subjecting the sample containing DNA to amplification via polymerase chain reaction (PCR) using a first set of primers which specifically amplify a first AAV region. The first AAV region is characterized by having at least 250 nucleotides of AAV capsid nucleic acid sequence, a variable sequence flanked by a sequence of at least 18 nucleotides at the 5? end of the first AAV region and a sequence of at least 18 nucleotides at the 3? end of the first AAV region. Each of the 5? and 3? at least 18 nucleotides is the same over at least 9 consecutive nucleotides relative to corresponding sequences in an alignment of at least two AAV serotypes. Each of the sets of primers consist of a 5? primer and a 3? primer. The method is further useful for identifying AAV sequences in the sample by the presence of amplified proviral AAV sequences.

  • Publication number: 20030092161
    Abstract: An efficient method of producing recombinant virus is described. The method involves transfecting an uncut, circular plasmid containing a recombinant viral genome, a first I-SceI recognition site located 5′ to the viral genome, and a second I-SceI recognition site located 3′ to the adenovirus genome into a host cell. The host cell is then cultured under conditions in which it expresses I-SceI endonuclease. The endonuclease cleaves the I-SceI recognition sites, thereby rescuing the recombinant virus from the plasmid, making it available for packaging into an infectious virus.
