　　pGL4.43載體簡介

　　The pGL4.43[luc2P/XRE/Hygro] Vector contains three copies of a xenobiotic response element (XRE) that drives transcription of the luciferase reporter gene luc2P (Photinus pyralis). luc2P is a synthetically-derived luciferase sequence with humanized codon optimization that is designed for high expression and reduced anomalous transcription. The luc2P gene contains hPEST, a protein destabilization sequence, which allows luc2P protein levels to respond more quickly than those of luc2 to induction of transcription. The vector backbone contains an ampicillin resistance gene to allow selection in E. coli and a gene for hygromycin resistance to allow selection of stably transfected mammalian cell lines.

　　Example Protocol

　　In this example protocol, the pGL4.43[luc2P/XRE/Hygro] Vector is used to measure

　　activation of the XRE in HepG2 cells upon treatment with TCDD. The pGL4.75 Vector

　　(encoding Renilla luciferase) is used as a normalization control. In designing such

　　experiments, it is important that the chosen cell type can be transfected efficiently and

　　that it expresses the proper components of the signaling pathway of interest in order to

　　generate the biological response. Protocol optimization may be required for your

　　particular cell type and assay conditions.
