Lentivirus expresses codon optimized Blue Fluorescent Protein (BFP) under an enhanced EF1a promoter. A Blasticidin (Bsd) selection marker was express under Rsv promoter, which allows to select transduced fluorescent positive cells.
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. See Product Manual (.pdf).
