PBAD SPL
Description
This is a page containing a synthetic promoter library (SPL) of pBAD promoters made by [http://2013.igem.org/Team:DTU-Denmark 2013 DTU iGEM team]. The library can be used to make and arabinose inducible system with very low leakiness, or tune the the promoter strength of the system when it's turned on.
A tight inducible system can be a very useful tool to express lethal or growth inhibiting proteins in E.coli. It can also be necessary with a non leaky expression system if you would like to visualize the expression of GFP SF in E.coli (see [http://2013.igem.org/Team:DTU-Denmark/HelloWorld link]).
The library
Here is a complete list of the sequences and their relative leakiness and strength:

a The sequence of each pBAD promoter characterized. To use this simply produce a primer with the promoter sequence you wish in a tail. Replace the old promoter in your system e.g. Part:BBa_K808000 with the new and see the chance. For more information go to ([http://2013.igem.org/Team:DTU-Denmark/pBAD_SPL link]).
b Inducibility = Induced Strength divided by leakiness.
