The pGL4.11[luc2P] Vector encodes the luciferase reporter gene luc2P (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 pGL4.11[luc2P] Vector is a basic vector with no promoter. However, it contains a multiple cloning region to allow cloning of a promoter of choice. The luc2P reporter gene contains hPEST, a protein destabilization sequence. The protein encoded by luc2P responds more quickly and with greater magnitude to changes in transcriptional activity than the luc2 gene, its more stable counterpart.
