Summary: PCR mutagenesis. PCR mutagenesis is simple method for generating site-directed mutagenesis. This method can generate mutations (base substitutions, insertions, and deletions) from double-stranded plasmid without the need for subcloning into M13-based bacteriophage vectors and for ssDNA rescue. The procedure involves a PCR reaction using a supercoiled plasmid vector as the template and two synthetic oligonucleotide primers containing the desired mutation with each complementary to the opposite strands of the vector. After PCR, the template (wild type) plasmid which is dam methylated in almost all E. coli is removed by digestion with Dpn I which is specific for methylated DNA. The mutated plasmid remains intact in the reaction.

- PCR Mutagenesis (Matt Lewis, Department of Pathology, University of Liverpool)
This method uses a proof-reading polymerase to read all the way around a plasmid and thus incorporate the primer as the new (mutant) sequence. Only a few (say 12) PCR cycles are performed on a relatively large amount of plasmid template to minimise the chance of expanding PCR sequence errors.

- PCR Mutagenesis Protocol (Michael Bumbulis, Baldwin-Wallace College)
PCR is based on the enzymatic amplification of a DNA fragment that is flanked by two oligonucleotide primers that anneal (stick) to opposite strands of the target sequence. The primers are oriented with their 3' ends pointing towards each other (recall that DNA is synthesized in the 5' to 3' direction). These primers are then extended by the polymerase enzyme. Repeated cycles of heat denaturation, annealing of the primers to their complementary sequences and extension of the primers result in the amplification of the segment defined by the 5' ends of the primers...

Site-directed Mutagenesis using PCR
PCR site-directed methods allow site-specific mutations to be incorporated in virtually any double-stranded plasmid; eliminating the need for M13-based vectors or single-stranded rescue.
