A method for site-directed mutagenesis which generates highly efficient plasmids and which uses only two PCR primers. The primers incorporate the same site for a restriction nuclease, the recognition site of which is 5' to the cut; the linear PCR product treated with such a nuclease, therefore, does not contain the recognition site, but leaves overhangs which facilitate re-cyclization. The interior of the plasmid contains the desired mutation sequence, and the sequence of the overhang may be designed to be the native sequence.Stemmer, W.P. and Morris, S.K. (1992) Biotechniques 13, 214-220
