To ensure the successful assembly and subsequent transformation of assembled DNAs, NEB recommends the following: After first use, store the kit components at indicated temperatures.
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. The following reagents are supplied with this product: coli (provided) or use directly in other applications. Prepare linearized vector by PCR amplification using a high-fidelity DNA polymerase or by restriction digestion.Ĭonfirm and determine concentration of fragments and linearized vector using agarose gel electrophoresis, a NanoDrop™ instrument or other method.Īdd fragments and linearized vector to Gibson Assembly Master Mix and incubate at 50☌ for 15 minutes to 1 hour, depending on number of fragments being assembled.
PCR amplify fragments using a high-fidelity DNA polymerase. Overview of Gibson Assembly Cloning Kit Protocol:ĭesign primers to amplify fragments (and/or vector) with appropriate overlaps 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. coli (NEB #C2987) were transformed with 2 μl of the master mix/fragment mixture using the transformation protocol on page 12. Overview of the Gibson Assembly Cloning Methodġ0 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☌ for 60 minutes. To help select the best DNA assembly method for your needs, please use our Synthetic Biology/DNA Assembly Selection Chart.įor help designing primers, please view our primer design video. 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). 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 DNA ligase seals nicks in the assembled DNA. The proprietary DNA polymerase fills in gaps within each annealed fragment. The exonuclease creates single-stranded 3´ overhangs that facilitate the annealing of fragments that share complementarity at one end (overlap region). The Gibson Assembly Master Mix includes three different enzymatic activities that perform in a single buffer: Gibson Assembly efficiently joins multiple overlapping DNA fragments in a single-tube isothermal reaction (1,2). It has been rapidly adopted by the synthetic biology community due to its ease-of-use, flexibility and suitability for large DNA constructs. It allows for successful assembly of multiple DNA fragments, regardless of fragment length or end compatibility.
