The Gibson Assembly® Method Overview

One of the essential technologies used by SGI-DNA is the Gibson Assembly® method, a revolutionary method developed by Daniel Gibson and colleagues at the J. Craig Venter Institute (JCVI).

Since its introduction to the life science community in 2009, the Gibson Assembly® method has become a mainstay in many synthetic biology laboratories and has attracted interest from both the academic and commercial life sciences community due to its ease-of-use, robustness and flexibility.

For non-commercial use, SGI-DNA Gibson Assembly® reagents do not require a license and there are never any royalties due. Contact us at info@sgidna.com with any questions and for licensing the Gibson Assembly® method for commercial use. SGI-DNA is the only provider of Gibson Assembly® commercial licenses, and charges a yearly fee with no royalties. We strive to make Gibson Assembly® easy and convenient to use for all scientific researchers.
