General description
This plasmid contains the BR322 (low copy number) origin of replication and provides approximately 20 plasmid copies per bacterial cell. It also contains the mammalian CMV promoter upstream of the MCS and Kan resistance for selection of transfected mammalian cells. Low copy number plasmids are useful for very large transgenes or for transgenes that can be toxic to bacterial cells.

Application
BR322 Information: BR322 is a wild type plasmid isolated from E.coli. It contains a low copy origin that allows for plasmid maintenance at a frequency of approximately 10-100 plasmid copies per cell. Typically this number is closer to 30-40 copies per cell. Most common cloning plasmids contain a derivative of the origin of replication in this plasmid called pUC. The pUC origin was created by removing the Rep repressor protein that normally regulates plasmid copy number in E.coli and also making a single point mutation in the origin of replication itself. The point mutation is the most important difference between the origin of replication.This plasmid can be used as a general purpose low copy cloning vector.

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

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

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.

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
