      DescriptionB18R-E3L RNA (human codon optimized for B18R and E3L)
      Background InformationSimplicon™ is a novel system to effect immediate high sustained protein expression of multiple genes into transfected cells without the risk of genome integration. The technology employs a single, synthetic, polycistronic, self-replicating RNA based on the Venezuelan equine encephalitis (VEE) genome1,2,3. The Simplicon™ RNA contains only genes encoding the VEE RNA replication machinery while the structural proteins that are required to make an infectious particle have been removed and replaced with the transgenes of interest.

      Introduction and replication of the Simplicon™ RNA is expected to elicit a strong interferon response in transfected cells. To suppress the IFN responses, a Vaccinia virus protein4, B18R, is used for the original Simplicon™ technology. Recently, we found that another Vaccinia virus protein4, E3L, also suppresses the IFN responses in Simplicon™ RNA expression. B18R neutralizes type I interferons by direct binding, while E3L inhibits the cytoplasmic signaling pathways of IFN responses. Therefore, B18R and E3L are both employed in the Simplicon™ Expression System and work collaboratively to suppress IFN responses. As a result, there is increased cell viability during RNA transfection and increased expression of the transgenes. The Simplicon™ Expression System works in human cells and is not expected to work in mouse cells. This is because the B18R does not effectively neutralize mouse interferon (IFN)-β.

      The B18R-E3L RNA (human codon optimized for B18R and E3L) is a synthetic polycistronic mRNA that is co-transfected with the Simplicon™ RNA to suppress the IFN responses. B18R-E3L RNA can also be used to prepare B18R conditioned medium by transfection into HFFs (Cat. No. SCC058). B18R-E3L RNA is also available for co-transfection of any mRNAs to suppress the IFN responses and enable repeated transfection of mRNAs. Please refer to the User Guide for Simplicon™ Expression System located on our website (www.emdmillipore.com).

      Components
      • B18R-E3L RNA (human codon optimized for B18R and E3L), human codon optimized: (Cat. # CS224503), One (1) vial containing 10 µL of RNA (1 µg/µL). Store at -80 °C.
      Applications
      ApplicationTo strongly suppress more interferon responses than single B18R to enable more expression of a Simplicon™ RNA or regular mRNA(s).
      Application Notes B18R-E3L RNA (human codon optimized for B18R and E3L) is provided as a polycistronic mRNA with both the B18R and E3L genes to more strongly suppress the interferon (IFN) responses that degrades Simplicon™ RNA(s) or regular mRNA(s). B18R RNA (E3L) works at single co-transfection with Simplicon™ RNA or repeated co-transfection with regular mRNA(s). B18R RNA (E3L) can also be used for production of B18R-CM (B18R-conditioned medium).
