The Next vivo system is made up of >40 unique parts encoding both protein and RNA components. The main focus of our team this year was to submit all 38 TX-TL protein components to the registry as a collection of parts that anyone could use to produce their own Next vivo system. Several of these TX-TL components were already in the registry but were under different expression control, lacked purification tags, and/or were not codon optimized for expression in E. coli. As such we sought to improve these parts for future use.
