iGEM Toolkits: Background


As with the expansion of the iGEM competition, many iGEM teams have started to investigate the possibility of working with large-scale genomes. Large-scale gene manipulation often requires the use of tools which allow multiple gene inserts as to bring the cloning project from single gene level to a multiple gene level. However, the current BioBrick standard vectors available through iGEM are not designed for multiple-insert cloning. Therefore, the UW iGEM team decided to research methods to improve cloning efficiency and as a result, two "toolkits" were submitted to the registry.



Gibson Assembly Toolkit

As an expansion of work started by the 2010 UW IGEM team, this year we developed and submitted a set of plasmid backbones for BioBricks that are optimized for Gibson assembly. Based on the bglBrick standard RFC 21, these "pGA" vectors comprise the Gibson Assembly Toolkit

What's in the Gibson Assembly Toolkit?
  • Five plasmid backbones
  • 2 High copy extraction/cloning vectors: pGA1A3, pGA1C3
  • 3 low copy assembly vectors: pGA3K3, pGA4A5, pGA4C5











Magnetosome Toolkit

In addition, we were also ambitious about assembling a large gene-construct of over 16 kb. Therefore, utilizing our pGA vectors and Gibson cloning methods, the Magnetosome Toolkit was developed with the goal to build magnetic E.Coli; a novel characteristic expressed solely by magnetotactic bacteria, such as Magnetospirillum magneticum strain AMB-1.

What’s in the Magnetosome Toolkit?

  • A set of the 18 essential genes for the various steps of magnetosome formation.
  • Our favorite genes in pGA vectors
  • A table compiling individual gene functions from our literature search
