Gibson assembly overview. The entire Gibson assembly reaction requires few components with minor manipulations. [3] The method can simultaneously combine up to 15 DNA fragments based on sequence identity. It requires that the DNA fragments contain ~20-40 base pair overlap with adjacent DNA fragments. These DNA fragments are mixed with a ...
Efficiently generating oligonucleotides beyond ~110 nucleotides in length is very difficult, so to insert a mutation further into a sequence than a 110 nt primer will allow, it is necessary to employ overlap extension PCR. In OE-PCR the sequence being modified is used to make two modified strands with the mutation at opposite ends, using the ...
A modification of this method, Gibson assembly, described by Gibson et al. allows for single-step isothermal assembly of DNA with up to several hundreds kb. By using T5 exonuclease to 'chew back' complementary ends, an overlap of about 40bp can be created. The reaction takes place at 50 °C, a temperature where the T5 exonuclease is unstable.
The MODAL strategy defines overlap sequences known as "linkers" to reduce the amount of customisation that needs to be done with each DNA fragment. The linkers were designed using the R2oDNA Designer software and the overlap regions were designed to be 45 bp long to be compatible with Gibson assembly and other overlap assembly methods. To ...

Gibson assembly is a quick cloning method that uses three primary enzymes; 5' exonuclease, polymerase and ligase. [15] The exonuclease digests the 5' end of DNA fragments leaving a 3' overhang. [15] If there is significant homology (20-40 bp) on each end of the DNA insert, it can anneal with a complementary backbone. [15]
