Genetic adjuvants for DNA vaccines with mutant IRF-3 gene | Increase Th1 response

pBOOST2-saIRF3 plasmids express a human or murine mutant interferon regulatory factor 3 (IRF-3) gene. IRF-3 has been shown to primarily increase Th1 T-cell responses [1].

A constitutively active form of IRF-3 was generated by creating a single point mutation of Ser396 to Asp. This super-activated IRF-3 presents a >10-fold enhanced transactivating potential over the wild-type IRF-3 for the IFN-α and IFN-β promoters [2].

pBOOST2-saIRF3 plasmids express the transgene under the control of the strong and ubiquitous EF-1α/HTLV composite promoter and are selectable in E. coli with Zeocin™.
