Abstract

The assembly of DNA fragments with homologous arms is becoming popular in routine cloning. For an in vitro assembly reaction, a DNA polymerase is often used either alone for its 3'-5' exonuclease activity or together with a 5'-3' exonuclease for its DNA polymerase activity. Here, we present a 'T5 exonuclease DNA assembly' (TEDA) method that only uses a 5'-3' exonuclease. DNA fragments with short homologous ends were treated by T5 exonuclease and then transformed into Escherichia coli to produce clone colonies. The cloning efficiency was similar to that of the commercial In-Fusion method employing a proprietary DNA polymerase, but higher than that of the Gibson method utilizing T5 exonuclease, Phusion DNA polymerase, and DNA ligase. It also assembled multiple DNA fragments and did simultaneous site-directed mutagenesis at multiple sites. The reaction mixture was simple, and each reaction used 0.04 U of T5 exonuclease that cost 0.25 US cents. The simplicity, cost effectiveness, and cloning efficiency should promote its routine use, especially for labs with a budget constraint. TEDA may trigger further development of DNA assembly methods that employ single exonucleases.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
