ViraPower™ HiPerform™ Promoterless Gateway™ Vector Kit (Invitrogen™)

The ViraPower™ HiPerform™ Promoterless Gateway™ Vector Kit contains the MultiSite Gateway™-adapted ViraPower™ HiPerform™ promoterless lentiviral expression vector, pLenti6.4⁄R4R2⁄V5-DEST™ for easy recombination-based cloning and lentiviral-based high-level expression of a target gene from any promoter of choice in dividing and non-dividing mammalian cells. The pLenti6.4⁄R4R2⁄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.

Advantages
• Generates replication-incompetent lentivirus for transducing dividing and non-dividing mammalian cells
• Easy, simultaneous, recombination-based cloning of multiple DNA fragments in a defined order and orientation using MultiSite Gateway™ technology
• Expression of the target gene under the control of a promoter of choice
• Stable, long-term 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.
• Promoterless vector to express the target gene under the control of a promoter of choice
• Blasticidin selection marker for stable selection under control of PGK promoter for long-term, persistent expression
