pTracer-CMV2是一个双表达框载体,CMV启动子后有MCS供插入外源基因;hEF1α启动子调控Cycle 3 GFP-Zeocin fusion的表达,可以做到既有荧光蛋白来做转染指示,且荧光基因表达和外源基因表达又不会互相干扰,而且Zeocin也可以用来做稳定性细胞筛选。另外,由于EM-7启动子的存在,Cycle 3 GFP-Zeocin fusion在E.coli中也可以表达,可以用来做原核荧光定位。 Three pTracer mammalian expression vectors are available that express GFP fused to the selectable marker Zeocin. Each vector uses a different set of promoters to express the gene of interest and the Cycle 3 GFP-Zeocin fusion. All three pTracer vectors have the following features: (1)Cycle 3 GFP-Zeocin fusion for selection in mammalian cell lines (2)BGH polyA signal and transcription termination sequences to enhance mRNA stability The pTracer-CMV2 vector offers: (1)CMV promoter for high-level constitutive expression of your gene of interest (2)EF-1α promoter for high-level constitutive expression of the Cycle 3 GFP-Zeocin fusion (3)Ampicillin resistance gene for selection in E. coli
