pLVX-AcGFP1-N1 is an HIV-1-based, lentiviral expression vector that allows you to express your gene of interest fused to AcGFP1, a green fl uorescent protein derived from Aequorea coerulescens. Genes cloned into the multiple cloning site (MCS), located upstream of the AcGFP1 coding sequence, are expressed as N-terminal fusions of the AcGFP1 protein. Expression of the fusion protein is driven by the constitutively active human cytomegalovirus immediate early promoter (PCMV IE) located just upstream of the MCS. Lentiviral particles derived from the vector allow the expression of AcGFP1 fusion proteins in virtually any cell type, including primary cells. The unmodifi ed vector expresses AcGFP1, and may be used to produce marker virus to optimize infection protocols.

pLVX-AcGFP1-N1 contains all of the viral processing elements necessary for the production of replication-incompetent lentivirus, as well as elements to improve viral titer, transgene expression, and overall vector function. The woodchuck hepatitis virus posttranscriptional regulatory element (WPRE) promotes RNA processing events and enhances nuclear export of viral and transgene RNA (1), leading to increased viral titers from packaging cells, and enhanced expression of your gene of interest in target cells. In addition, the vector includes a Rev-response element (RRE), which further increases viral titers by enhancing the transport of unspliced viral RNA out of the nucleus (2). Finally, pLVX-AcGFP1-N1 also contains a central polypurine tract (cPPT) element that increases nuclear importation of the viral genome during target cell infection, resulting in improved vector integration and more effi cient transduction (3).

In addition to lentiviral elements, pLVX-AcGFP1-N1 contains a puromycin resistance gene (Puror ) under the control of the murine phosphoglycerate kinase (PGK) promoter (PPGK) for the selection of stable transductants. The vector also contains a pUC origin of replication and an E. coli ampicillin resistance gene (Ampr ) for propagation and selection in bacteria.
