An easy-to-produce non-integrating option for constitutive mouse IL-23 expression

With the CAGs-mIL-23 Enhanced Episomal Vector (EEV), you can get sustained, long-lasting, and non-viral expression of the mouse IL-23 gene from a non-integrating vector. Driven by the constitutive CAG promoter, the CAGs-mIL-23 EEV works in most cell types, including primary cells and stem cells, and can even be directly injected into mice.

CAGs-mIL-23 Enhanced Episomal Vector (EEV)

With virtually no limits on insert size (unlike AAV vectors) Enhanced Episomal Vectors (EEVs) are an excellent choice for non-integrating, non-viral gene expression. Because they replicate in synchrony with the host cell, they are stably inherited and can be used for long-lasting expression—up to several months both in vitro and in vivo—without modifying the host genome. SBI’s EEV System, which is an enhanced version of the Epstein-Barr Nuclear Antigen-1 (oriP-EBNA1) system, offers:

  • High levels of expression
  • Easy to clone formats
  • No special plasmid production
  • Nonviral, non-integrating technology
  • Constitutive and inducible vector formats

Sustained, non-integrating expression of mouse IL-23 in vivo via EEV

A constitutive EEV reporter based on CAGs-MCS leads to higher serum IL-23 levels in mice than two other episomal vector systems

Figure 1. A constitutive EEV reporter based on CAGs-MCS leads to higher serum IL-23 levels in mice than two other episomal vector systems. We compared SBI’s EEV system to two other episomal vector systems—minicircle technology1 and the mini-intronic plasmid system2—using a mouse IL-23 cDNA cloned into the three different vectors. We introduced the three vectors or vehicle only into mice using hydrodynamic tail vein delivery (HDD). After seven days, we measured serum IL-23 levels using an ELISA assay and found that the EEV technology outperformed the other episomal platforms by at least 10-fold, demonstrating the ability of the EEV platform to provide sustained, long-lasting transgene expression.
