pEF1alpha-DsRed-Express2 Vector
pEF1α-DsRed-Express2 is a mammalian expression vector that constitutively expresses the red fluorescent protein DsRed-Express2, even after stable integration of the vector into the host cell genome. Stable, constitutive expression of DsRed-Express2 is driven by the human elongation factor 1 alpha (EF1α) promoter, which allows the protein to be expressed without the transgene silencing associated with CMV promoters. The vector, which lacks an MCS, is designed to be used for cell labeling or as a marker of transfection efficiency.
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.
