Invitrogen™ BLOCK-iT™ Lentiviral Pol II miR RNAi Expression System

Combines Invitrogen's BLOCK-iT Pol II miR RNAi and ViraPower™ Lentiviral technologies to facilitate creation of a replication-incompetent lentivirus that delivers a microRNA (miRNA) sequence of interest to dividing or non-dividing mammalian cells for RNA interference (RNAi) analysis

Catalog No. K493700

Description

Broadens the potential RNAi applications beyond those of other traditional retroviral systems (Naldini, 1998). The BLOCK-iT Lentiviral Pol II miR RNAi Expression System includes:
o A BLOCK-iT Pol II miR RNAi Expression Vector Kit for production of an expression clone containing a double-stranded oligonucleotide encoding a pre-miRNA sequence for expression in mammalian cells. The BLOCK-iT Pol II miR RNAi Expression Vector (pcDNA™6.2-GW/miR) provides a rapid and efficient way to clone ds oligo duplexes encoding a desired miRNA target sequence into a vector containing a Pol II promoter (CMV) for use in RNAi analysis. The BLOCK-iT Pol II miR RNAi Expression Vector is specifically designed to allow expression of miRNA sequences and contain specific miR flanking sequences that allow proper processing of the miRNA.
o The pDONR™221 vector to transfer the premiRNA expression cassette into the lentiviral expression plasmid using Gateway™ Technology. The Gateway Technology is a universal cloning method that takes advantage of the site-specific recombination properties of bacteriophage lambda (Landy, 1989) to provide a rapid and highly efficient way to move your DNA sequence of interest into multiple vector systems.
o A pLenti6/V5-DEST destination vector into which the pre-miRNA cassette from the expression clone is transferred using Gateway Technology. This expression plasmid contains elements that allow packaging of the construct into virions and the Blasticidin resistance marker for selection of stably transduced cell lines.
o Gateway BP and LR Clonase™ II Enzyme Mixes that facilitate the transfer of the pre-miRNA expression cassette from the expression vector into the
pLenti6/V5-DEST destination vector.
o Components of the ViraPower Lentiviral System for production of a replication-incompetent lentivirus that stably expresses the miRNA of interest in both dividing and non-dividing mammalian cells. The ViraPower Lentiviral Technology facilitates highly efficient, in vitro or in vivo delivery of a target gene or RNA to dividing and non-dividing mammalian cells using a replication-incompetent lentivirus. Based on the lentikat™ system developed by Cell Genesys (Dull et al., 1998), the ViraPower Lentiviral Technology possesses features which enhance its biosafety while allowing high-level expression in a wider range of cell types than traditional retroviral systems.
