This vector contains a CMV promoter that allows the expression of a transgene in mammalian cells. The plasmid also includes the internal ribosome entry site (IRES) from Foot and Mouth Disease Virus (FMDV) which allows two proteins to be translated from the same mRNA molecule. In this vector there is a yellow fluorescent protein (YFP) reporter gene after the IRES. FMDV IRES expression is often signficantly lower (typically 20-30 fold lower by total protein weight) than the gene upstream of the IRES. The reporter in this plasmid is called Kringle YFP and was developed by DNA2. 0.

Promoter Expression Level: Promoter and IRES Expression Level: This plasmid contains the mammalian CMV promoter to drive gene expression. We have tested all of our mammalian promoters in a range of cell types and CMV is consistently the strongest in those we have studied. However there are many reports of the CMV promoter demonstrating silencing by methylation in long-term culture. The IRES that is used to drive YFP expression from the CMV promoter is considerably weaker than the CMV promoter and typically yields >20 fold lower protein levels.
