The pGL4.70[hRluc] Vector encodes the hRluc gene (Renilla reniformis) and is designed for high expression and reduced anomalous transcription. The pGL4 Vectors are engineered with fewer consensus regulatory sequences and a synthetic gene, which has been codon optimized for mammalian expression. The pGL4.70[hRluc] Vector is a basic vector with no promoter. However, it contains a multiple cloning region that allows for cloning of a promoter of choice.
