NEBuilder® HiFi DNA Assembly Bundle for Large Fragments
NEBuilder HiFi DNA Assembly Master Mix has been reformulated with components containing Recombinant Albumin (rAlbumin) beginning with Lot #10238675.
Product Introduction
NEB recommends NEB 10-beta Competent E. coli, High Efficiency (NEB #C3019) for assemblies larger than 15 kb. NEBuilder® HiFi DNA Assembly Bundle for Large Fragments offers a discount for purchasing these competent cells with the NEBuilder HiFi DNA Assembly Master Mix.
NEBuilder HiFi DNA Assembly Master Mix was developed to improve the efficiency and accuracy of DNA assembly. This method allows for seamless assembly of multiple DNA fragments, regardless of fragment length or end compatibility. This method has been used to assemble either single-stranded oligonucleotides or different sizes of DNA fragments with varied overlaps (15–30 bp). It has utility for the synthetic biology community, as well as those interested in one-step cloning of multiple fragments due to its ease of use, flexibility and simple master-mix format. Visit NEBuilderHifi.com for more information.

Product Information
Description
(USA Customers: Please note you will receive two separate boxes when you order this product; one box will contain the competent cells on dry ice; the other box will contain NEBuilder HiFi DNA Assembly Master Mix on wet ice.)
NEB recommends NEB 10-beta Competent E. coli (High Efficiency, NEB #C3019) for assemblies larger than 15 kb. NEBuilder HiFi DNA Assembly Bundle for Large Fragments offers a discount for purchasing these competent cells with NEBuilder HiFi DNA Assembly Master Mix.
NEBuilder HiFi DNA Assembly was developed to improve the efficiency and accuracy of DNA assembly. This method allows for seamless assembly of multiple DNA fragments, regardless of fragment length or end compatibility. This method has been used to assemble either single-stranded oligonucleotides or different sizes of DNA fragments with varied overlaps (15-30 bp). It has utility for the synthetic biology community, as well as those interested in one-step cloning of multiple fragments due to its ease of use, flexibility and simple master-mix format. The reaction includes different enzymes that work together in the same buffer (see Figure 1):
- The exonuclease creates single-stranded 3´ overhangs that facilitate the annealing of fragments that share complementarity at one end (the overlap region)
- The polymerase fills in gaps within each annealed fragment
- The DNA ligase seals nicks in the assembled DNA
NEBuilder HiFi DNA Assembly kits are available in various formats: with NEB 5-alpha chemically competent cells (Cloning Kit, NEB #E5520), as a bundle with NEB 10-beta chemically competent cells (Bundle for Large Fragments, NEB #E2623) and without competent cells (Master Mix, NEB #E2621) . NEB 5-alpha chemically competent cells are excellent for routine assemblies of 15kb or less. NEB recommends NEB 10-beta Competent E. coli (High Efficiency, NEB #C3019 ) or NEB 10-beta Electrocompetent E. coli (NEB #C3020) for assemblies larger than 15kb. If the assembled genes contain repetitive sequences, NEB Stable Competent E. coli (NEB #C3040) should be used.
NEBuilder has been used in various applications, including:
- Site-directed mutagenesis
- Construction of an sgRNA-Cas9 expression vector | Animation
- Assembly of linear yeast expression cassettes

Properties & Usage
Materials Required but not Supplied
DNA Polymerase (for generating PCR products):For generating PCR Products, we recommend Q5® High-Fidelity DNA Polymerase (NEB #M0491 ) or related products, such as Q5 Hot Start High-Fidelity DNA Polymerase (NEB #M0493 ) or Q5 Hot Start High-Fidelity 2X Master Mix (NEB #M0494 ).
LB (Luria-Bertani) plates with appropriate antibiotic. For selection of transformed competent cells, we recommend LB plates with appropriate antibiotic.
Features
Benefits over GeneArt Gibson Assembly and In-Fusion Snap Assembly:
- Enjoy less screening/re-sequencing of constructs, with virtually error-free, high-fidelity assembly.
- Join DNA fragments together more efficiently, even with larger fragments or low DNA inputs
- Use NEBuilder HiFi in successive rounds of assembly, because it removes 5´ and 3´ end mismatches. (Save time by avoiding time-consuming PCR amplification steps.)
- Bridge two ds-fragments with a synthetic ss-DNA oligo for simple and fast construction (e.g. linker insertion or gRNA library)
- Use with lower DNA input requirements
- Switch from other systems easily, because NEBuilder HiFi is compatible with Gibson Assembly®- and In-Fusion- designed fragments
- No licensing fee requirements from NEB for the NEBuilder products
Benefits over Traditional Cloning:
- Save time with Simple and Fast Seamless Cloning
- Use one system for both "standard-size" cloning and larger gene assembly products, up to 11 fragments.
- Move on with your workflow, because DNA can be used immediately for transformation or as template for PCR or RCA.
- Adapts easily for multiple DNA manipulations, including site-directed mutagenesis.

Product Notes
- You will receive 3 separate products when you order this bundle: 2X (NEB #E2621S) and 1X (NEB #C3019H) (competent cells will arrive in a separate box containing dry ice).
- Store the NEBuilder HiFi DNA Assembly Master Mix and positive controls at -20°C. Store the NEB 10-beta/ Stable Outgrowth Medium at 4°C. Store the competent cells at -80°C.
- To ensure the successful assembly and subsequent transformation of assembled DNAs, NEB recommends the following:
DNA:PCR product purification is not necessary if the total volume of all PCR products is 20% or less of the assembly reaction volume. Higher volumes of PCR products may reduce the efficiency of high-fidelity DNA assembly and transformation due to the elevated carryover amounts of PCR reaction buffer and unused primers present in the PCR product. Column purification of PCR products may increase the efficiency of both high-fidelity DNA assembly and transformation by 2-10 fold and is highly recommended when performing assemblies of three or more PCR fragments or assembling longer than 5 kb fragments. Purified DNA for assembly can be dissolved in ddH2O (Milli-Q® water or equivalent is preferable), TE or other dilution buffers. - Insert: When directly assembling fragments into a cloning vector,the concentration of assembly fragments should be at least 2 times higher than the concentration of vector. For assembly of 4 or more fragments into a vector, we recommend using an equimolar ratio of fragments.
- Biology: Some DNA structures, including inverted and tandem repeats, are selected against by E. coli. Some recombinant proteins are not well tolerated by E. coli and can result in poor transformation or small colonies.
