Separation of plasmid from chromosomal DNA is based on coprecipitation of the cell wall-bound chromosomal DNA with the insoluble complexes containing salt, detergent, and protein.

Purification of plasmids is central to molecular cloning. A purified plasmid can be used for many standard applications, such as sequencing and transfections into cells.
