pLVX-EF1alpha-IRES-ZsGreen1 Vector
pLVX-EF1α-IRES-ZsGreen1 is a bicistronic lentiviral expression vector that can be used to generate high-titer lentivirus for transducing virtually any dividing or nondividing mammalian cell type, including primary and stem cells. The vector contains an internal ribosomal entry site (IRES) that allows a gene-of-interest and the ZsGreen1 fluorescent protein to be simultaneously coexpressed from a single mRNA transcript. Expression of the transcript is driven by the constitutively active human elongation factor 1 alpha (EF1α) promoter.
Expression of AcGFP1 driven by the EF-1 alpha promoter in stem cell lines is higher than expression driven by the CMV promoter
Expression of AcGFP1 driven by the EF-1 alpha promoter in stem cell lines is higher than expression driven by the CMV promoter. The mouse embryonic stem cell lines E14 (Panel A) and D3 (Panel B) were transduced by Lenti-X lentivirus, expressing AcGFP1 either under the control of the CMV promoter or the Elongation factor alpha (EF-1 alpha) promoter. The expression level of AcGFP1 in infected cells five days postinfection was monitored by FACS analysis using the FL1 channel. The expression of AcGFP1 driven by the EF-1 alpha promoter in both stem cell lines was considerably higher compared to the CMV promoter. This is mainly due to a considerably lower rate of silencing of the EF-1 alpha promoter in stem cells compared to the CMV promoter as published (Wang, et al. (2008) Stem Cells Dev 17:279–289).
