载体描述: 

由于IRES元件的存在,pIRES可以同时表达两个基因。两个基因在转录水平上基本一致,但是在翻译水平上差异较大。有数据称,IRES后面的基因,表达量约只有IRES前面的基因的二分之一甚至三分之一。很多研究者在将pIRES2-EGFP转染至细胞后,会发现绿色荧光很少很弱,其中一个原因就是IRES元件的特性所致。因此,如果您要同时表达两个地位相等的基因,那么还是建议您采用双表达框载体,例如Invitrogen的pBudCE4.1、Invivogen的pVitro2-neo-mcs、Yrbio的pYr-adshuttle-3等。这些载体上都有两个外源基因表达框,分别由两个不同的强启动子驱动,可以实现两个基因的同时表达,且表达强度也非常可观。

载体抗性: 

卡那霉素(Kanamycin)

载体描述: 

Epitope tags provide a method to localize gene products in living cells, identify associated proteins, track the movement of tagged proteins within a cell, and characterize new genes without creating protein-specific antibodies. The pCMV-Tag1 vector contains both the synthetic FLAG epitopell ll and the c-myc epitope from the human c-myc gene. The pCMV-Tag1 vector allows production of fusion proteins in a variety of conformations. The pCMV-Tag2-5 vectors allow either c-myc or FLAG epitope tagging at either the C- or N-terminus. Each pCMV-Tag2-5 vector is supplied with all three reading frames for easy cloning and expression. The small size of the FLAG (eight amino acids long) and c-myc epitope tags (ten amino acids long) decreases the possibility of interference with the tagged protein. The FLAG and c-myc epitopes are recognized by the anti-c-myc and anti-FLAG antibodies, which can be used to characterize the target protein. The pCMV-Tag vectors allow high-level expression of tagged proteins in mammalian cells. Expression is driven by the human cytomegalovirus (CMV) immediate early promoter. The CMV promoter provides constitutive expression of cloned genes in a wide variety of cell lines. The translational start sequence used in the pCMV-Tag1, pCMV-Tag2 and pCMV-Tag3 vectors is a 10-base Kozak consensus sequence of CGG(A/G)CCATGG. pCMV-Tag4 and pCMV-Tag5 vectors do not contain a translation start sequence. Stable clone selection is made possible with G418 by the presence of the neomycin-resistance gene. The pCMV-Tag vectors are only 4.3 kb, allowing easy cloning and vector manipulations. This small size is due to the single antibiotic selection marker used by both prokaryotic and mammalian cells. The neomycin-resistance gene provides stable selection in mammalian cells with G418 driven by the SV40 promoter and kanamycin selection in E. coli cells driven by the bla (ß-lactamase) promoter.
