RBS Characterization
For our RBS characterization project, 5 different RBS sequences from the [http://partsregistry.org/Ribosome_Binding_Sites/Prokaryotic/Constitutive/Anderson Anderson RBS family] (J61100, J61101, J61107, J61117, J61127) and one known RBS ([http://partsregistry.org/Part:BBa_B0032 B0032]) where placed in front of GFP and measured over 18 hours using a Gen5 fluorenscence and absorbance plate reader. The map of the construction is shown below.

We've also looked at mRNA folded shapes using mfold to see if there was a common pattern in the Anderson RBS shapes. This might have been usable in predicting RBS strength for the other untested Anderson RBS sequences. Unfortunately, this didn't seem to be the case, as all the tried RBS sequences had very different mfold shapes.
