The ViraPower™ HiPerform™ T-REx™ Gateway® Vector Kit contains the Gateway®-adapted ViraPower™ HiPerform™ tetracycline-regulated lentiviral expression vector, pLenti6.3⁄TO⁄V5-DEST™ for easy recombination-based cloning and lentiviral-based, regulated, high-level expression of a target gene in dividing and non-dividing mammalian cells. The pLenti6.3⁄ TO⁄ V5-DEST™ vector is equipped with two key genetic elements, making it a HiPerform™ vector: the Woodchuck Posttranscriptional Regulatory Element (WPRE) and the central Polypurine Tract (cPPT) sequence from the HIV-1 integrase gene to produce at least 4-fold increase in protein expression compared to vectors lacking these elements.

• Generates replication-incompetent lentivirus for transducing dividing and non-dividing mammalian cells
• Easy recombination-based cloning using Gateway® technology
• Stable, long-term, tetracycline-regulated expression
• Enhanced protein expression, up to 4-fold or greater, compared to traditional lentiviral expression systems

Key Features
• WPRE from the woodchuck hepatitis virus, increases transgene expression and cPPT from the HIV-1 integrase gene, increases the copy number of lentivirus integrating into the host genome, thus increasing viral titer. WPRE and cPPT together produce at least a four-fold increase in protein expression in most cell types, compared to other vectors that do not contain these elements.
• Hybrid promoter consisting of the human cytomegalovirus (CMV) promoter and two tetracycline operator 2 (TetO2) sites for high-level, regulated expression of the target gene
• Blasticidin selection marker for stable selection under control of SV40 promoter

Kit includes
• pLenti6.3⁄TO⁄V5-DEST™ vector
• pLenti3.3⁄TR vector
• pLenti6.3⁄TO⁄V5-GW⁄lacZ plasmid
• Tetracycline
• One Shot® Stbl3™ Chemically Competent E. coli (Cat # C737303)
• pENTRTM Gus positive control plasmid.
