Using PCR to extend the limit of oligonucleotide synthesis.

ABSTRACT

A method has been developed to allow one to extend the practical limit of oligonucleotide synthesis by coupling the synthesis reaction to a subsequent PCR. Given that DNA synthesizers are capable of producing reasonable yields of oligonucleotides that are 125-150 bases in length, this method could be used to recover the minute amount of full-length product present in mixtures extended well beyond the established limits. This technology could be applied to gene synthesis and mutagenesis.
