Three components constitute our transcription factor development pipeline. The first is a selection system which lyses cells containing strong matches between a mutated transcription factor and its promoter and allows for the speedy recovery of the relevant DNA. The second component 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 component is an ''in vitro'' characterization system called MITOMI that allows high-throughput quantitative analysis of DNA-protein interaction strengths.

== Other New parts ==

In developing these three pillars, a number of parts were made. We have listed all of them here and have highlighted our favorites.
-
Our lysis selection device uses what we refer to as the wild-type T7 Promoter:

=== Systems ===

[http://partsregistry.org/Part:BBa_K613001 K613001]
+
'''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).  
-
In addition, we submitted the following mutants:

'''In Vivo Characterization''': We cloned an RFP gene under control of T7 promoter variants (parts BBa_K613001 through BBa_K613012) into a low copy number plasmid (pSB3K1, formerly BBa_I739202). We also cloned TetR mutants (parts BBa_K613013 through BBa_K613019) into a  a low copy number plasmid (pSB3K1, formerly BBa_I739202). Both sets of plasmids were thoroughly characterized using IPTG platereader experiments.

'''In Vitro Characterization''': We characterized TetR mutants (parts BBa_K613013, BBa_K613015, BBa_K613016, BBa_K613017, BBa_K613019) in the low copy number plasmid pSB3K1 (formerly BBa_I739202).

== Favourite parts ==

[http://partsregistry.org/Part:BBa_K613003 K613003]

Our three favourite parts are TetR mutants, characterised ''in-vivo'' using our reporter systems, and ''in-vitro'' by MITOMI.

We submitted a family of T7 promoters with varying strength. Our lysis selection device uses what we refer to as the wild-type (100% reported strength) T7 Promoter:
