Opis

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.
