WebCopy number An important consideration in choosing what plasmid backbone to use is the copy number. For example, cloning is best done with a high copy plasmid (e.g. pUC) as plasmid preps will have a higher yield. Expressing a toxic gene is better from a low to medium copy plasmid(e.g. pET which uses the pBR322 origin), as there are fewer copies.
