Plasmid Purpose:

This vector allows transcription of un-polyadenylated and un-capped RNA using the T7 bacteriophage polymerase. This plasmid also contains the internal ribosome entry site (IRES) from Encephalomyocarditis virus (ECMV) between the promoter and the multiple cloning site (MCS). It is designed to be used to express genes using eukaryotic T7 expression systems such as those used for the recovery of a variety of viruses. This vector is not designed for the expression of two proteins from the same mRNA. For this purpose we have designed pSF-CMV-MCS-IRES-PciI where the PciI site contains a start codon in the correct position for the IRES to express efficiently. In this vector there is an NcoI site (which contains an ATG start codon) in the correct position to enable efficient expression of a gene in the MCS.

Transcription Termination:

This plasmid contains three alternative transcription terminators for mammalian bacterial and bacteriophage (T7) expression. This means that only the promoter needs to be changed to alter the expression system you are using. We sell multiple promoters that can be used in each of these systems. The presence of each terminator does not reduce expression in the alternative systems.
