摘要：

The invention relates to a novel system for producing recombinant adenoviruses (rAd). The areas of application of said system are medicine, veterinary medicine, biotechnology, genetic engineering, and functional genomic analysis. The inventive system for producing rAds preferably consists of a donor virus, the packaging signal of which is (i) partially deleted and (ii) is surrounded by parallel recognition cites for a site-specific recombinase; a packaging cell line which expresses the site-specific recombinase; and donor plasmids containing (i) at least one recognition site for the site-specific recombinase, (ii) the full viral packaging signal, (iii) optionally two recognition sites for a rarely cutting restriction endonuclease, and (iv) insertion sites for foreign DNA or inserted foreign DNA.
