Amplifying an entire double-stranded plasmid by an inverse polymerase chain reaction (PCR) using a pair of tail-to-tail primers is a particularly efficient approach for introducing changes into DNA sequences. However, the approach generally works best for plasmids less than 5 Kb and it can be difficult to amplify the large multicomponent vectors that are used for protein expression in various eukaryotic cells. We have therefore adopted an alternative approach in which two smaller PCR products are generated and then ligated to produce, the complete plasmid. A mutagenic primer is used to introduce the desired change and each reaction includes one of a pair of tail-to-tail primers from within an antibiotic resistance gene contained on the plasmid so that the two PCR products contain complementing parts of the complete gene. Ligating the two products generates various combinations but only the correctly ligated molecules recreate the antibiotic resistance gone and are able to replicate in Escherichia coli. When combined with methods to minimize the carryover of template plasmid, this can be an efficient way of introducing mutations into large plasmids.
