Collections/Cell-Free TX-TL

This collection is a user contributed collection, and is not under curation by iGEM HQ/Registry.

Next vivo

Our part collection will contain all the major biomolecules required for a cell-free transcription-translation system providing them in an easy to express and purify way that anyone can easily produce for their experimental purposes. These biomolecules include:

  • 38 Transcription and Translation (TX-TL) protein genes codon optimized for E. coli expression
  • 20 Next vivo MS2-tagged tRNA isolation genes
  • 2 MS2-tagged ribosomal rRNA genes for isolation of functional ribosomes from the cell lysate


TX-TL Proteins: The initial focus for this collection was submitting all 38 TX-TL protein genes, codon optimized, hexahistidine tagged, and under the control of a T7 promoter system for controlled expression. We have submitted and characterized 9 of these parts to the registry in pSB1C3, characterized expression of 17 parts, and are working toward completing the remaining parts following the competition.

tRNA: The tRNA component of the Next vivo system was another of our focuses for this years project. Currently, no simple protocol exists for efficient and specific isolation of tRNA from the cell. We are happy to announce that we were able to develop a system that allows for the purification of specific, fully modified tRNA from cell lysate. The first tRNA in our part collection is that of tRNAPhe. With the success of our purification strategy, we plan to synthesize the remaining tRNA in our expression construct for submission into this collection.

Ribosomes: Currently we plan to BioBrick both the 23S and 16S E. coli ribosomal rRNA genes with the MS2 hairpin added into either sequence at a region that places it externally on the 3D ribosome structure. This design has previously been used before by another research lab to purify whole ribosomes using the MS2 binding protein tagged with a hexahistidine tag.

MS2BP: The MS2 binding protein is a central component to our tRNA and ribosome purification strategies. It was previously submitted by the 2016 Lethbridge iGEM team and we feel it would be a great addition to our Next vivo Part Collection.

Validation: Finally, we have also included our measurement control construct for the complete TX-TL system. This part expresses a RNA Spinach tagged EYFP mRNA and EYFP protein, that in the addition of DFHBI produces both green and yellow fluorescence indicating transcription and translation respectively.
