pEF1alpha-IRES-DsRed-Express2 Vector
pEF1α-IRES-DsRed-Express2 is a bicistronic mammalian expression vector that allows the simultaneous, constitutive expression of a protein of interest and the red fluorescent protein DsRed-Express2. Expression of the bicistronic transcript is driven by the human elongation factor 1 alpha (EF1α) promoter.
Robust expression of DsRed-Express2 in mouse bone marrow hematopoietic stem and progenitor cells
Robust expression of DsRed-Express and DsRed-Express2 in mouse bone marrow hematopoietic stem and progenitor cells. Mononuclear bone marrow cells were transduced with retroviral vectors encoding DsRed-Express (Panel A), DsRed-Express2 (Panel B), or EGFP (Panel C), and fluorescent cells were sorted 87 hr later. Red and green fluorescence signals were detected using the PE and FITC filter sets, respectively. The lines represent gates defined by analyzing untransduced cells.
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).
