Our project uses 3 major new technologies: Multiplex Automated Genome Engineering (MAGE), chip-based synthesis of DNA, and lamba red recombination, along with more traditional bioinformatics. We hope that future iGEM teams will also use these techniques in their own synthetic biology projects. | Our project uses 3 major new technologies: Multiplex Automated Genome Engineering (MAGE), chip-based synthesis of DNA, and lamba red recombination, along with more traditional bioinformatics.

Overview | MAGE | Chip-Based Synthesis | Lambda Red | Protocols
Our project uses 3 major new technologies: Multiplex Automated Genome Engineering (MAGE), chip-based synthesis of DNA, and lamba red recombination, along with more traditional bioinformatics. We hope that future iGEM teams will also use these techniques in their own synthetic biology projects.
Bioinformatics
See our bioinformatics page for details on the computer aspects of our technology.
Zinc Finger Binding Site Finder
Check out our Zinc Finger Binding Site Finder Tool here! This tool was used to search the human genome for the six target DNA sequences that we used to design our custom zinc finger arrays.
Chip-Based Synthesis
We are creating 55,000 zinc fingers using microchip synthesis. These fingers will then be tried against the DNA sequences we wish to bind.

MAGE
Multiplex automated genome engineering (MAGE) is a new method for large-scale programming and evolution of cells. MAGE simultaneously targets many locations on the chromosome, thus producing combinatorial genomic diversity.

Lambda Red- Mediated Recombineering
Genes can be altered by recombination with linear DNA molecules. This requires a high internal DNA concentration, achievable by electroporation. The lambda red system allows efficient recombination between homologous sequences as short as 40 bp, which frees us of the need to provide long tracts of homology for recombination into the chromosome.

Gibson (Isothermal) Assembly
An isothermal, single-reaction method for assembling multiple overlapping DNA molecules by the concerted action of a 5′ exonuclease, a DNA polymerase and a DNA ligase.
