CRKL基因RNA干扰慢病毒载体的构建与鉴定

目的 构建CBKL基因RNA干扰(RNAi)慢病毒载体.方法 将筛选确定的CRKL基因RNAi有效靶序列克隆到pGCL-GFP载体[含U6启动子和绿色荧光蛋白(GFP)]连接产生LV-shCRKL慢病毒载体.通过酶切、测序验证后,用LV-shCRKL、pHelper 1.0和pHelper2.0质粒共转染包装细胞293T细胞,包装产生慢病毒,以293T细胞GFP蛋白的表达水平测定病毒滴度.结果 载体片段插入正确.共转染包装细胞293T能产生高浓度的重组慢病毒LV-shCRKL.结论 成功构建了人CRKL基因RNAi病毒载体.

Construction and verification of Ientiviral CRKL gene RNA interfering vector

Objective To construct a lentiviral vector carrying CRKL gene RNA interfering( RNAi ).Methods The CRKL RNAi was selected and subcloned into the lentiviral vector,pGCL-GFP(including U6 promotor and green fluorescent protein),generating the lentiviral vector LV-shCRKL.The corrected CRKL was confirmed by endoenzyme digestion ,sequencing.Recombinant lentiviruses were produced by 293T cells following the eo-transfection of LV-shCRKL,with the packaging plasmids pHelper1.0 and pHelper2.0.The virus titer was detected by GFP expressions in 293T cells.Results Plasmid LV-shCRKL carried the correct sequence.The recombinant lentiviruse LV-shCRKL could be produced by co-transfection of LV-shCRKL to 293T cells.Conclusion The recombinant lentiviruse vector LV-shCRKL is constructed successful.
