The pGL4.10[luc2] Vectorencodes the luciferase reporter gene luc2 (Photinus pyralis) 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 pGL4.10[luc2] Vector is a basic vector with no promoter. However, it contains a multiple cloning region to allow cloning of a promoter of choice.
