| abstract |
The present invention relates to the preparation of novel vector systems which are generated by in-vitro recombination, using gene technology, of nucleic acids from foamy virus species and of exogenous nucleic acid, and are produced by suitable host cells or by recombinantly altered packaging cell lines. The recombinant preparation of particularly suitable packaging cell lines is likewise a constituent of this invention. The invention is distinguished by the safe and efficient transfer by foamy virus vectors of therapeutic and other genes into eukaryotic cells. |
