Most site-directed mutagenesis protocols strongly recommend that you use only PAGE- or HPLC-purified primers to mutate plasmid templates. Using purified primers is supposed to minimize the introduction of unintended mutations, thus drastically improving the probability of generating your desired mutant. However, specially purified primers can be extremely expensive, and take longer to synthesize than standard [...]
Three Approaches to Site-directed Mutagenesis
Site-directed mutagenesis studies can be extremely useful for elucidating the function of a gene or protein, or for creating variants of an enzyme with new and improved functions. There are now many approaches available for generating site-directed mutants, whatever your purpose. In this post I’ll summarize three techniques that will enable you to produce a [...]
