Gibson Assembly was developed by Dr. Daniel Gibson and his colleagues at the J. Craig Venter Institute and licensed to NEB by Synthetic Genomics, Inc. It allows for successful assembly of multiple DNA fragments, regardless of fragment length or end compatibility. It has been rapidly adopted by the synthetic biology community due to its ease-of-use, flexibility and suitability for large DNA constructs.

Gibson Assembly efficiently joins multiple overlapping DNA fragments in a single-tube isothermal reaction (1,2). The Gibson Assembly Master Mix includes three different enzymatic activities that perform in a single buffer:
  • The exonuclease creates single-stranded 3´ overhangs that facilitate the annealing of fragments that share complementarity at one end (overlap region).
  • The proprietary DNA polymerase fills in gaps within each annealed fragment. 
  • The DNA ligase seals nicks in the assembled DNA.

The end result is a double-stranded fully sealed DNA molecule that can serve as template for PCR, RCA or a variety of other molecular biology applications, including direct transformation. The method has been successfully used by Gibson’s group and others to assemble oligonucleotides, DNA with varied overlaps (15–80 bp) and fragments hundreds of kilobases long (1–2).

Overview of the Gibson Assembly Cloning Method

Overview of the Gibson Assembly Cloning Method


Specification:

10 μl of 2X Gibson Assembly Master Mix was incubated with 6 fragments (5 fragments of 400 bp and one of 2,780 bp, with 40 bp overlap, 0.05 pmol each) in a final volume of 20 μl at 50°C for 60 minutes. NEB 5-alpha Competent E. coli (NEB #C2987) were transformed with 2 μl of the master mix/fragment mixture using the transformation protocol on page 12. Greater than 100 white colonies were observed when 1/10 of the outgrowth was spread on an ampicillin plate with IPTG/Xgal and incubated overnight.

Overview of Gibson Assembly Cloning Kit Protocol:
  • Design primers to amplify fragments (and/or vector) with appropriate overlaps
  • PCR amplify fragments using a high-fidelity DNA polymerase. 
  • Prepare linearized vector by PCR amplification using a high-fidelity DNA polymerase or by restriction digestion.
  • Confirm and determine concentration of fragments and linearized vector using agarose gel electrophoresis, a NanoDrop™ instrument or other method.
  • Add fragments and linearized vector to Gibson Assembly Master Mix and incubate at 50°C for 15 minutes to 1 hour, depending on number of fragments being assembled.
  • Transform into NEB 5-alpha Competent E. coli (provided) or use directly in other applications.

Properties & Usage

Materials Required but not Supplied

DNA Polymerase (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).

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 into a cloning vector.

  • Storage Note:
    The kit is shipped on dry ice. Upon arrival, store kit at -80°C. After first use, store the kit components at indicated temperatures.

  • Usage notes:

    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 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 at least 2–3 times higher than the concentration of vector. For assembly of multiple fragments into a vector, we recommend using equimolar ratio of fragments.
    • Transformation: NEB 5-alpha Competent E. coli (High Efficiency, NEB #C2987) provided with the kit are recommended for use for assembled products of less than 20 kb in size. It is also possible to use other NEB competent E. coli strains, with the exception of BL21, BL21(DE3), Lemo21(DE3) and Nico21(DE3). For example, Shuffle T7 Express Competent E. coli can be used for the expression of a difficult to express protein. When using competent E. coli from a vendor other than NEB, we have seen decreased robustness of transformation with the Gibson Assembly reaction.
    • 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. Should you require the use of Electrocompetent cells, please use the Electrocompetent Cells Transformation Protocol.
