As dicussed in

Selection of vector -

Based on:

  • size of the gene of interest
  • presence of ori size 
  • copy number of plasmid
  • restriction enzyme sites
  • antibiotic resistance genes as a selectable markers  

- wherein

The copy number of plasmid decides the power of replication inside the host. Usually, high copy number (>100) is used to express the protein.
