Abstract

Here, we describe a method that offers a unique way to engineer plasmids with precision but without digestion using restriction enzymes for the insertion of DNA. The method allows the insertion of PCR fragments in between any two nucleotides within a target plasmid. The only requirement is that the amplified fragments must be embedded between DNA sequences homologous to the site in which the integration is planned. This method is an adaptation of the QuikChange Site-Directed Mutagenesis protocol. It is simpler than the existing cloning strategies and is suitable for multiparallel constructions of new plasmids. We have demonstrated its utility by constructing plasmids in which we have successfully integrated PCR fragments up to 1117 bp.
