ABSTRACT:
The subject of the invention is retroviral gene transfer vectors in which foreign sequences are introduced between the retroviral primer binding site (PBS) and the retroviral splice donor (SD). The efficiency of gene expression is improved by this modification, and the vectors are characterized by an increased reliability during use.
