    Abstract: Retroviral vector constructs are described which have a 5′ LTR, a tRNA binding site, a packaging signal, one or more heterologous sequences, an origin of second strand synthesis and a 3′ LTR, wherein the vector construct lacks retroviral gag/pol or env coding sequences. In addition, gag/pol, and env expression cassettes are described wherein the expression cassettes lack a consecutive sequence of more than 8 nucleotides in common. The above-described retroviral vector constructs, gag/pol and env expression cassettes may be utilized to construct producer cell lines which preclude the formation of replication competent virus.

    Abstract translation: 描述了具有5'LTR,tRNA结合位点,包装信号,一个或多个异源序列,第二链合成起始和3'LTR的逆转录病毒载体构建体,其中载体构建体缺乏逆转录病毒gag / pol或env 编码序列。 此外,描述了gag / pol和env表达盒,其中表达盒缺少共同超过8个核苷酸的连续序列。 上述逆转录病毒载体构建体,gag / pol和env表达盒可用于构建排除形成复制能力的病毒的生产细胞系。
