SGI-DNA announced the launch of the Gibson Assembly Ultra Kit which allows researchers to perform complex, large, and multiple fragment assemblies in a simple, two-step reaction. This Gibson Assembly Ultra Kit is the second kit in SGI's growing Gibson Assembly portfolio utilizing the Gibson Assembly method. The first kit launched was the Gibson Assembly HiFi 1 Step Kit, a high fidelity formulation that significantly reduces errors/mutations at the cloning junctions, enabling researchers to assemble up to 5 fragments in a one hour, one-step reaction.

The Gibson Assembly method was developed in 2009 by Dan Gibson, Ph.D., and his colleagues at the J. Craig Venter Institute during the team's quest to construct the first synthetic cell. Since its introduction to the life science community, 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. The Gibson Assembly Ultra Kit is available in 3 sizes: 5 reactions (starter kit), 10 reactions and 50 reactions.

Mastermixes are sold separately.
