With constant advances both in the development of new enzymes (e.g., PaqCI®, BsaI-HF®v2 and BsmBI-v2) and research on maximizing enzyme functionality (e.g., ligase fidelity), NEB has become the industry leader in pushing the limits of Golden Gate Assembly (and related methods such as MoClo, GoldenBraid, Mobius Assembly and Loop Assembly). NEB has all the products and information you need to perform complex assemblies.
Fidelity decreases as the complexity of Golden Gate Assembly increases. Visit our protocols for multi-fragment assemblies to the right.
Advances in ligase fidelity
Research at NEB has led to an increased understanding of ligase fidelity, including the development of a comprehensive method for profiling end-joining ligation fidelity in order to predict which overhangs have improved fidelity (1, 2, 3). Their research has enabled complex fragment assemblies with high efficiencies and >90% accuracy. Use our Ligase Fidelity Tools to design high fidelity Golden Gate Assemblies under various experimental conditions.
Type IIS restriction enzymes for Golden Gate Assembly
NEB offers more Type IIS (i.e., recognize asymmetric DNA sequences and cleave outside of their recognition sequence) restriction enzymes than any other supplier, many of which are used in Golden Gate Assembly. NEB is pleased to offer: Esp3I (an isoschizomer of BsmBI that is recommended for use at 37°C and is supplied with rCutSmart™Buffer), PaqCI (an AarI isoschizomer with a 7 basepair recognition sequence) and the improved BsaI-HFv2 and BsmBI-v2, which are optimized for Golden Gate Assembly.

Find out how Golden Gate Assembly can be used to quickly join multiple DNA fragments.
Type IIS restriction enzymes have both recognition and binding sites, but cut downstream of the recognition site, creating 4-base overhangs ideal for re-assembly. View a list of TypeIIS enzymes.
Advances in understanding ligase fidelity, bias, and efficiency in Golden Gate Assembly allows for assembly of more than 50 fragments in a single reaction.
