General description
PSF-CMV-CMV-SBFI - dual CMV expression plasmid is a versatile expression vector for the production of two proteins under the control of two separate CMV promoter expression cassettes in mammalian cells. This vector also contains a Kanamycin resistance cassette for growth and maintenance in E. coli.
Promoter Expression Level: This plasmid vector contains the mammalian CMV promoter to drive gene expression. We have tested all of our mammalian promoters in a range of cell types and CMV is consistently the strongest in those we have studied. However there are many reports of the CMV promoter demonstrating silencing by methylation in long-term culture.

Application
First multiple cloning site notes: There is start codon in the NcoI site that can be removed by digestion with KpnI if required. The first MCS for gene insertions extends from NotI to XbaI but the Shine-Dalgarno sequences and Kozak sequences are aligned with the start codon in the NcoI restriction site. The ClaI to NheI sites have other functions such as adding peptide tags or IRES elements. The BsgI and BseRI restriction sites cleave within the stop codon in the XbaI site and allow the retrospective fusion of coding sequences. These sites are normally only used on genes that we sell in the main multiple cloning site.
Second multiple cloning site notes: The second MCS in PSF-CMV-CMV-SBFI - dual CMV expression plasmid extends from PspOMI to SpeI. This MCS contains a Kozak sequence immediately upstream of the start codon in the PciI restriction site. We insert the start codons of our genes into here where possible.
This MCS has been designed to be compatible with genes that are within our main MCS by using enzymes sites in the same order that produce compatible cohesive ends that can be ligated together. This allows genes to be transferred from the main MCS (NotI to NheI) into the second MCS (PspOMI to SpeI) is required. Enzymes that are compatible between these two MCSs include:

- SalI compatible with XhoI
- PciI compatible with NcoI and BspHI
- AclI compatible with ClaI
- SpeI compatible with XbaI and NheI Avr2

The efficacy of vaccine adjuvants such as Toll-like receptor agonists (TLRa) can be improved through formulation and delivery approaches. Here, we attached small molecule TLR-7/8a to polymer scaffolds (polymer-TLR-7/8a) and evaluated how different physicochemical properties of the TLR-7/8a and polymer

Dickkopf-3 (Dkk-3) is a secreted protein whose expression is downregulated in many types of cancer. Endogenous Dkk-3 is required for formation of acini in 3D cultures of prostate epithelial cells, where it inhibits transforming growth factor (TGF)-β/Smad signaling. Here, we

Recycling of signaling proteins is a common phenomenon in diverse signaling pathways. In photoreceptors of Drosophila, light absorption by rhodopsin triggers a phospholipase Cβ-mediated opening of the ion channels transient receptor potential (TRP) and TRP-like (TRPL) and generates the visual

The Notch3 signaling pathway is thought to play a critical role in cancer development, as evidenced by the Notch3 amplification and rearrangement observed in human cancers. However, the molecular mechanism by which Notch3 signaling contributes to tumorigenesis is largely unknown.
