- 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 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).To help select the best DNA assembly method for your needs, please use our Synthetic Biology/DNA Assembly Selection Chart.For help designing primers, please view our primer design video.
  Overview of the Gibson Assembly 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. 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 Master Mix 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 DNApolymerase or by restriction digestion.
  - Confirm and determine concentration of fragments using agarose gel electrophoresis, a Nanodrop™ instrument or other method
  - Add DNAs to Gibson Assembly Master Mix and incubate at 50°C for 15minutes to 1 hour, depending on number of fragments being assembled.
  - Transform into E. coli or use directly in other applications
