Abstract

The availability of custom synthetic gene-length DNA products removes numerous bottlenecks in research efforts, making gene synthesis an increasingly common commercial service. However, the assembly of synthetic oligonucleotides into large, custom DNA constructs is not especially difficult, and performing “in-house” gene synthesis has time and cost advantages. This unit will treat both the concerns of design and physical assembly in gene synthesis, including how to design DNA sequences for synthesis and the design of overlapping oligonucleotide schemes to ensure facile assembly into the final product. Assembly is accomplished using a reliable series of PCR reactions, with a troubleshooting assembly protocol included, which not only assembles difficult sequences but allows identification of the source of a failure down to a pair of oligonucleotides.
