IRES

This acts as an initiation for eukaryotic ribosomes and begins translation of the following protein sequence. We compared two different IRESs: the classical EMCV IRES used in many papers,which has been shown to be compatible with replicons and the NKRF IRES derived from the 3’UTR of the mammalian NF-kappaB repressing factor, which we also chose to test because during investigation regarding the efficacy and strength of the EMCV IRES, the NKRF derived IRES was shown to be 30-fold more efficient however had never been previously used in Huh7.
