摘要:
A retroviral vector that eliminates cis-acting retroviral elements, which are not useful to and may cause problems for, an integrated provirus utilizes a recombination system, such as the bacteriophage P1 cre-lox recombination system. A gene of interest and a loxP site are inserted into a long terminal repeat, which is then duplicated. The enzyme cre is inserted between the long terminal repeats and combines them. The structure of the resulting provirus in the host genome is that of a single, long terminal repeat carrying a single copy of the gene of interest. Following infection, the retrovirus produces proviral structures having only a single long terminal repeat.
