pTriEx-4 Neo DNA - Novagen

The pTriEx<TMSYMBOL></TMSYMBOL>-4 Neo vector is designed to allow rapid characterization of target genes in E. coli, insect and vertebrate cells, and to allow rapid selection of stable transfected vertebrate cells expressing high levels of target gene. Expression in vertebrate cells is mediated by the CMV immediate early enhancer and promoter². The drug selection marker is expressed under the control of the EMC virus Cap-Independent Translation Enhancer (CITE) sequence (or IRES), allowing rapid selection of transfected vertebrate cells using the drug G418 or neomycin sulfate. For expression in insect cells, pTriEx-4 Neo contains flanking baculovirus sequences to permit the generation of recombinant baculoviruses using the BacVector<TMSYMBOL></TMSYMBOL> System. In baculovirus-infected insect cells, expression is driven by the very late p10 promoter. Expression in E. coli is regulated by the tightly controlled T7lac promoter. Expression can be induced in hosts such as NovaBlue by infecting with λCE6, a phage that constitutively expresses T7 RNA polymerase from the λlp_L and λp_I promoters. Alternatively, pTriEx recombinant plasmids can be transferred into a (DE3)pLacI host that allows induction with IPTG. Native protein can be expressed by cloning into the Nco I site, or generated by cloning into the PshA I or Sma I sites and cleaving the fusion protein with enterokinase or thrombin, respectively.
