Gibson Assembly

Theory

Gibson Assembly as a scar free method of DNA recombination that is highly efficient and readily copes with combination of multiple DNA fragments at once.

Practice

Master Mix for Gibson Assembly

Reagent Volume/µl
Taq ligase (40u/µl) 50
5x isothermal buffer 100
T5 exonuclease (1u/µl) 2
Phusion polymerase (2u/µl) 6.25
Nuclease-free water 216.75 Total 375

Master Mix is 1.33x concentrated

In order to join 3 fragments together add 1µl of each fragment (previously amplified by PCR) to a PCR tube along with 9µl of the master mix above.
