More Information
Summary:The invention relates to retroviral producer cell comprising nucleic acid sequences encoding: gag and pol proteins; envelope protein or a functional substitute thereof; amplifiable selection marker; and the RNA genome of the retroviral vector particle, wherein said nucleic acid sequences are all integrated at a single locus within the retroviral producer cell genome. The invention also relates to nucleic acid vectors comprising a non-mammalian origin of replication and the ability to hold at least 25 kilobases (kb) of DNA, characterized in that said nucleic acid vector comprises retroviral nucleic acid sequences encoding: gag and pol proteins, and an env protein or a functional substitute thereof. The nucleic acid vector additionally comprises nucleic acid sequences encoding an amplifiable selection marker. The invention also relates to uses and methods using said nucleic acid vector in order to produce stable retroviral packaging and producer cell lines.
