Abstract
A method for performing site-directed mutagenesis characterized in that the method includes the step of carrying out PCR by the use of a double-stranded DNA vector having one or more amber codons, the vector resulting from insertion of a target DNA fragment for site-directed mutagenesis, and at least two kinds of selection primers; and a kit for site-directed mutagenesis for use in the above method, characterized in that the kit includes amber codon reversion primers. According to the present invention, there can be provided a method for performing site-directed mutagenesis and a kit, which is useful for genetic engineering or protein engineering, more simply and rapidly. By using the method and the kit of the present invention, it is possible to efficiently obtain a mutation-introduced gene at the desired position by simply transforming a host with a PCR product obtained by PCR.
