<p>We used a microfluidic based approach for characterizing TF mutants in vitro. The <a href="/Team:EPF-Lausanne/Tools/MITOMI">MITOMI</a> method allows us to measure absolute binding affinities and specificities of transcription factors. We determined the precise binding energy landscape of the wild type TetR transcription factor. We also generated several TetR transcription factor mutants and determined the specificities of a number of the new variants.</p>

<p>To be able to determine the in vivo activity and specificity of novel transcription factor variants we generated a suite of <a href="/Team:EPF-Lausanne/Our_Project/Assembly">reporter plasmid systems</a>. We successfully characterized a number of our reporter systems for functionality. We created a number of reporter plasmids to measure TetR activity, which lead to improved characterization data for the Partsregistry.</p>
