ABOUT
Dual reporter plasmids - Ferritin promoters - Lucia luciferase & SEAP
The expression plasmids pVITRO2-Lucia/SEAP are developed mainly for in vitro studies.
pVITRO2-Lucia/SEAP allows the ubiquitous and constitutive co-expression of two reporter genes: Lucia (secreted luciferase) and SEAP (secreted embryonic alkaline phosphatase).
They can be used either as a control vector or for cloning of open reading frames (ORF). Both reporter genes are flanked by unique sites (BspH I/Avr II for Lucia luciferase and Nco I/Nhe I for SEAP) that allow for convenient cloning of ORFs.
pVITRO2-Lucia/SEAP plasmids can be stably transfected in mammalian cells, and the reporter genes are expressed at high levels. pVITRO2-Lucia/SEAP plasmids carry two human ferritin composite promoters, FerH (heavy chain) and FerL (light chain). To eliminate the iron regulation, their 5’UTRs have been replaced by the 5’UTR of the mouse and chimpanzee EF-1α genes.
These plasmids are available with different selectable markers that are active both in E. coli and mammalian cells.
All products are for research use only, and not for human or veterinary use.

Details
• hFerH and hFerL composite promoters: Ferritin is a 24 subunit protein composed of two subunit types, termed H (heavy) and L (light). Ferritin is ubiquitously expressed. Its synthesis is highly regulated by the iron status of the cell. To eliminate the iron regulation of the ferritin promoters, the 5’UTR of FerH and FerL have been replaced by the 5’UTR of the mouse and chimpanzee elongation factor 1 (EF1) genes, respectively.
• SV40 enhancer which is comprised of a 72-base-pair repeat allows the enhancement of gene expression in a large host range. The enhancement varies from 2-fold in non-permissive cells to 20-fold in permissive cells.
• CMV enhancer: The major immediate-early enhancer of the human cytomegalovirus (HCMV) is composed of unique and repeated sequence motifs. The HCMV enhancer can substitute for the 72-bp repeats of SV40 and is severalfold more active than the SV40 enhancer.
• SV40 pAn: the Simian Virus 40 late polyadenylation signal enables efficient cleavage and polyadenylation reactions resulting in high levels of steady-state mRNA.
• pMB1 ori: a minimal E. coli origin of replication to limit vector size, but with the same activity as the longer Ori.
• FMDV IRES: The internal ribosome entry site of the Foot and Mouth Disease Virus enables the translation of two open reading frames from one mRNA with high levels of expression.
• EM7 is a bacterial promoter that enables the constitutive expression of the antibiotic resistance gene in E. coli.
• Antibiotic resistance gene :
- Resistance to Blasticidin S is conferred by the bsr gene from Bacillus cereus.
- hph gene confers resistance to Hygromycin B both in E. coli and mammalian cells.
- The neo gene from Tn5 confers resistance to Kanamycin in E.coli and G418 in mammalian cells.
In bacteria, the resistance gene is expressed from the constitutive E. coli EM7 promoter. In mammalian cells, the resistance gene is transcribed from the rat EF-1α promoter as a polycistronic mRNA and translated via the FMDV IRES.
• EF1 pAn is a strong polyadenylation signal.
• Lucia luciferase gene: Lucia is a secreted luciferase with strong bioluminescent activity.
