Gibson Assembly™ employs three enzymatic activities in a single-tube reaction: 5´ exonuclease, the 3´ extension activity of a DNA polymerase and DNA ligase activity. The 5´ exonuclease activity chews back the 5´ end sequences and exposes the complementary sequence for annealing. The polymerase activity then fills in the gaps on the annealed regions. A DNA ligase then seals the nick and covalently links the DNA fragments together. The overlapping sequence of adjoining fragments is much longer than those used in Golden Gate Assembly, and therefore results in a higher percentage of correct assemblies. The NEB Gibson Assembly Master Mix (NEB #E2611) and Gibson Assembly Cloning Kit (NEB #E5510S) enable rapid assembly at 50˚C.

In this webinar, you will learn about our recently developed a single-molecule sequencing method to characterize end-joining ligase fidelity (discrimination against ligating mismatched overhangs) and bias (sequence preferences) for short cohesive ends in a high throughput manner. This method allows determination of the relative frequency of all ligation products with or without mismatches, the position-dependent frequency of each mismatch, and sequence-dependent biases in ligation efficiency. We have applied the fidelity and bias data to optimize design of Golden Gate-type assemblies, allowing selection of overhang sets with minimized mismatch potential and high efficiency.  more
