The genome of avian adeno-associated virus was cloned for construction of gene transfer vectors. AAAV was propagated in special pathogen-free chicken embryo using the chicken embryo lethal orphan virus as the helper virus. The double-stranded genomic DNA was extracted from precipitated AAAV viron and cloned into pCR 2.1 vector.
