1. General notes:
   We highly recommend using our web tool, NEBuilder™ to design PCR primers with overlapping sequences between the adjacent DNA fragments and for their assembly iinto a cloning vector.
   
   
2. Usage notes:
   
   To ensure the successful assembly and subsequent transformation of assembled DNAs, NEB recommends the following:
   
   • Cells: Transformation efficiency of competent cells can vary by several logs. Perceived assembly efficiency directly correlates to the competence of the cells used for transformation.
   • Electroporation: Electroporation can increase transformation efficiency by several logs. When using the Gibson Assembly Master Mix product for electroporation, it is necessary to dilute the reaction 3-fold and use 1 μl for transformation.
   • DNA: PCR product purification is not necessary if the total volume of all PCR products in the Gibson Assembly reaction is 20% or less of the Gibson Assembly reaction volume. Higher volumes of PCR products may reduce the efficiency of Gibson 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 Gibson 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 2–3 times higher than the concentration of vector. For assembly of 3 or more fragments, we recommend using equilmolar 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.

1. I am not sure whether to choose NEBuilder HiFi DNA Assembly or NEB Gibson Assembly? How are the products different?
2. What are the advantages of this method compared to traditional cloning methods?
3. How large a DNA fragment can I assemble?
4. How many fragments of DNA can be assembled in one reaction?
5. What are the shortest overlaps that can be used with this assembly method?
6. What are the longest overlaps that can be used with this method?
7. Can ≤ 200 bp dsDNA fragments be assembled by this method?
8. Can ssDNA oligonucleotides be combined and assembled with dsDNA fragments?
9. Can longer or shorter incubation times be used?
10. Will the reaction work at other temperatures?
11. Is it necessary to inactivate restriction enzymes after vector digestion?
12. I would like to produce overlapping dsDNA fragments by PCR. Do I need to use PCR primers that have been purified by PAGE or HPLC?
13. I would like to assemble ssDNA oligonucleotides into dsDNA fragments. Do I need to use oligonucleotides that have been purified by PAGE or HPLC?
14. Can I use a 15-nt overlap that is entirely composed of His-tag repeats (i.e. CACCACCACCACCAC)?
15. Can you PCR-amplify the assembled product?
16. What should I do if my assembly reaction yields no colonies, a small number of colonies, or clones with the incorrect insert size following transformation into E. coli?
17. How can I reduce the number of vector-only background colonies?
18. What type of competent cells are suitable for transformation of DNA constructs created using Gibson Assembly?
19. Can I use electroporation instead of chemical transformation?
20. Are there any differences between the Gibson Assembly Master Mix (NEB #E2611) and Gibson Assembly Master Mix included in the Gibson Assembly Cloning Kit (NEB #E5510)?
21. Are there any differences between the requirements for 2-3 fragmentassemblies versus 4–6?
22. The Gibson Assembly Master Mix control reaction is not giving me any colonies. Why?
23. When using a polymerase that doesn't contain a 3'-5' exonuclease activity (such as Taq DNA Polymerase) to amplify fragments to be used in a Gibson Assembly reaction, should I be concerned about the potential 3' mismatch generated by the addition of a non-templated nucleotide?
24. Is storing Gibson Assembly Master Mix at -80°C harmful?
25. I would like to use NEBuilder but am concerned about user data privacy. How does NEB handle the information that I enter into NEBuilder?
26. Can I Use other primer design tools such as SnapGene for Gibson Assembly, to design primers for NEBuilder HiFi DNA Assembly?
27. What antibiotic resistance is encoded in the NEBuilder Positive Control (assembly control)?
