Amplification of plasmid is desirable for many applications including gene cloning, DNA sequencing, transfection, and probe preparation. The fastest and routinely used method to amplify plasmid is to introduce plasmid in an appropriate strain of E. coli e.g., DH5α (the process is called transformation), grow them to a suitable culture volume, and finally, extract plasmid from them (the process called plasmid isolation).
