For colours we could use the click beetle luciferase [http://partsregistry.org/wiki/index.php/Part:BBa_J70005 red] or [http://partsregistry.org/wiki/index.php/Part:BBa_J70006 green]. They're reliable and from the Knight lab but not in the distribution.

IMPORTANT INFO
The Photorhabdus luminescens [http://partsregistry.org/Part:BBa_J70008 luxCDABE operon] in the registry. It's not well characterised

[http://departments.kings.edu/biology/lux/bacterial.html Vibrio plasmid experiment] -possible source of lux operon

[http://departments.kings.edu/biology/lux/index.html] - Transformation protocol for students from basics - includes several plasmids

Plan
- set plasmid 555 into a BioBrick
- replace the promoter? sensitivity tuners?

Firefly luciferase is in the registry as [http://partsregistry.org/Part:BBa_I712019 BBa_I712019], and have been sent to us as part of the spring 2010 distribution.

We need to find a new vector with a bacterial ribosyme binding site, initiator, and a stop codon. Having searched via the catalog in the plasmids section, then in expression plasmids, we have selected a constitutive plasmid:
- The plasmid selected is [http://www.partsregistry.org/Part:BBa_J13002 BBa_J13002], which is a TetR repressed POPS/RIPS generator, again part of the spring 2010 distribution - kit plate 1, well 13B, plasmid pSB1A2. It was proven to work by UMN iGEM 2009.
