The pGL4.50[luc2/CMV/Hygro] Vector encodes the luciferase reporter geneluc2(Photinus pyralis), which has been codon optimized for mammalian expression. This vector also is engineered with fewer consensus regulatory sequences for reduced backgrounds and a decreased risk of anomalous transcription. This vector contains the following features:luc2reporter gene for expression in mammalian cells; CMV promoter for high translational expression; SV40 late poly(A) signal sequence is positioned downstream ofluc2to provide efficient transcription termination and mRNA polyadenylation; Binding region for RV primer 3 and RV primer 4; Synthetic poly(A) signal/transcription start site; Synthetic Hygromycin B-resistance gene for mammalian cell selection of the plasmid; Plasmid replication origin; Amprgene for bacterial selection for vector amplification.
