Lentivirus expresses codon optimized Red Fluorescent Protein (RFP) under an enhanced EF1a promoter. A Neomycin (Neo) selection marker was express under Rsv promoter, which allows to select transduced fluorescent positive cells. See Product Manual (.pdf).
The re-engineered EF1a promoter is strong constitutive promoter. It is non-tissue specific, highly expressed in all cell types, and less likely be silenced after long-term culture.
