摘要
We have developed an efficient method for the simultaneous introduction of up to three mutations in a plasmid DNA via homologous recombination. The strategy is compatible with a variety of mutations, including degenerate codons in plasmids of different sizes. In contrast to other methodologies, this approach employs the same set of reagents for both single- and multi-site mutagenesis assays, minimizes the required protocol steps, and exhibits remarkably high mutagenesis efficiencies.
