Are you looking for an all-in-one toolkit to build up your dream construct to try expressing your enzymes of choice, tailored to your lab’s resources and needs? A toolkit containing different promoters, RBSs, linkers, tags, reporters? This collection might be for you.

A collection of >100 DNA parts designed to be assembled in one-pot reaction using BsaI-based Golden-Gate assembly. DNA parts are MoClo, SEVA, Loop and CIDAR assembly compatible. The collection includes:

  • 3 promoters 
  • 7 RBS and insulators
  • 9 purification tags, 3 localization signals
  • 5 cleavage sites, flexible linkers
  • 23 genes of which 5 are reporters and 18 are used in diagnostics
  • 3 destination vectors

The Protein Expression Toolkit is shipped as purified and dried down plasmid DNA stained with Cresol Red in two 96-well plates. Each well contains approximately 50 ng of DNA. Cresol Red will not impact plasmid transformation.

What can it be used for:

Use the DNA parts of the collection to assemble the expression plasmids for the protein of your choice, tailored to the resources present in your lab. The collection enables thousands of combinations for each gene of choice. Full power of the collection can be explored using pipetting robots. The collection is compatible with all the CDSs present in the Open Enzyme collections.

Assembly Scheme


If you've already received the kit, check out the layout for Plate 1 and Plate 2.

This kit is included in kit plate 2 of the 2022 iGEM distribution. The plate map for kit plate 2 of the iGEM 2022 distribution can be found here
