[An effective method for site-directed mutagenesis in plasmids and cloning single-stranded DNA fragments]. / Effektivnyi metod napravlennogo vvedeniia mutatsii v plazmidy i klonirovaniia odnotiazhevykh fragmentov DNA.

ABSTRACT

A three primer variant of the earlier devised oligonucleotide-directed mutagenesis in plasmids is described, useful also for the fast cloning of single-stranded DNA products of the asymmetric polymerase chain reaction (PCR). Using this method for plasmid pHD-001-14-11, a 59 b. p. deletion and a 7 b. p. insertion were simultaneously introduced at 81% frequency, and the PCR-copied phage fd transcription terminator (26 b. p.) was inserted with the yield of 67%.
