The pGL4.12[luc2CP] Vector encodes the luciferase reporter geneluc2CP(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 optimized for mammalian expression. The pGL4.12[luc2CP] Vector is a basic vector with no promoter. However, it contains a multiple cloning region to allow cloning of a promoter of choice. Theluc2CPreporter gene contains hCL1 and hPEST, both of which are protein destabilization sequences. The protein encoded byluc2CPresponds more quickly and with greater a magnitude to changes in transcriptional activity than theluc2gene, its more stable counterpart.
