Site-Directed Mutagenesis (SDM) allows for changes in the DNA sequence of plasmids using polymerase chain reaction (PCR). It is a reliable, accessible, and rapid method which is the common initial step of many biochemial or genetic experiments. Here we describe the various different forms of SDM before giving a detailed method for the introduction of substitutions, insertions, or deletions using a fast, ligation-free protocol, followed by colony PCR to screen for mutated sequences.
