Abstract

Gene synthesis by chemical methods provides a powerful tool for modifying genes and exploring their structure, expression, and function in the post-genomic era. However, a bottleneck in recent gene synthesis technologies is the high cost of oligonucleotide synthesis and post-synthesis sequencing. Here, we describe a simple, rapid, and low-cost gene synthesis method based on overlap extension PCR (OE-PCR) and the DNAWorks program. This method enables DNA sequences with sizes ranging from 200 bp to 3 kb to be synthesized with few errors, and these errors can be easily corrected by site-directed mutagenesis. Thus, it is amenable to automation for the multiplexed synthesis of different genes and has a potential for high-throughput gene synthesis.
