These seven reporter vectors contain response elements (ARE, p53 RE, AT6 RE, MRE, HSE, HRE and XRE) that are important in various stress signaling pathways, the firefly luciferase gene and hygromycin resistance for selection in cells.
- Firefly Luciferase Reporter Vectors with Cellular Stress Response Elements
- Offer a range of response elements that are involved in stress signalling pathways
- Each vector included an optimized firefly luciferase gene that codes a reporter with a one-hour half-life
- Hygromycin resistance selectable marker means choosing transient transfection or generating a stable cell line
Creating a cell line with an indicator of a functional signaling pathway is useful for deciphering the components in a signaling pathway. These tools are made by inserting multiple repeats of a response element upstream of a minimal promoter (minP). We offer vectors that report the activity of a variety of cellular stress pathways using the optimized firefly luciferase gene luc2 in the pGL4 backbone. The luc2 gene is engineered to remove most cryptic transcription factor binding sites and improve mammalian expression through codon optimization. The luc2P and luc2CP and RapidResponse genes are luc2 genes appended with degradation sequences to influence the cellular half-life of the luc2 gene. The RapidResponse genes respond more rapidly to stimuli but at the expense of signal intensity. The luc2P (1-hour half-life) gene responds more rapidly than luc2 (3-hour half-life) with moderate signal intensity. These response element vectors also have a hygromycin resistance selectable marker for use either in transient transfection experiments or for selection of a stable cell line. To speed research, several pre-designed response element vectors based on the pGL4.27 Vector are available. Some of these also are available stable cell lines (GloResponse Cell Lines). The stress signaling pathway vectors available include oxidative stress in pGL4.37[luc2P/ARE/Hygro] Vector, DNA damage in pGL4.38[luc2P/p53 RE/Hygro] Vector, endoplasmic reticulum stress in pGL4.39[luc2P/ATF6 RE/Hygro] Vector, heavy metal stress in pGL4.40[luc2P/MRE/Hygro] Vector, heat shock in pGL4.41[luc2P/HSE/Hygro] Vector, hypoxia in pGL4.42[luc2P/HRE/Hygro] Vector and xenobiotic stress in pGL4.43[luc2P/XRE/Hygro] Vector.
