Overview
Summary
There are three pillars that underlie our transcription factor development pipeline. The first pillar is a selection system which lyses cells containing strong matches between a transcription factor and its promoter and allows for the speedy recovery of the relevant DNA. The second pillar is an in vivo characterization system that uses two different reporter systems as a way to document the binding affinities of the TetR transcription factor and its promoter pTet. The third pillar is an in-vitro characterization system called MITOMI that allows for high-throughput analysis of DNA-protein interaction strengths.
In developing these three pillars, a number of parts were made. We have listed all of them and have highlighted our favorites.
Systems
Selection System: We cloned the Berkeley Lysis cassette (BBa_K112808) under control of the T7 promoter into a low copy number plasmid (pSB3K1, formerly BBa_I739202).
