This product has been discontinued.

The pTriEx™-2 Neo vector is designed to allow rapid characterization of target genes in multiple expression systems, and to allow rapid selection of stable transfected mammalian cells expressing high levels of target protein. With this vector a single recombinant plasmid can be used to test expression in E. coli, insect and vertebrate cells. Expression in vertebrate cells is mediated by a hybrid promoter composed of the CMV immediate early enhancer fused to the chicken β-actin promoter. 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 mammalian cells using the drug G418 or neomycin sulfate. For expression in insect cells, pTriEx-2 Neo contains flanking baculovirus sequences to permit the generation of recombinant baculoviruses using the BacVector^® 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 λp_L and λp_I promoters. Alternatively, pTriEx recombinant plasmids can be transferred into a (DE3)pLacI host that allows induction with IPTG.
