Lab work

Hydrocarbon Sensing

Yesterday's digestion products were checked on a gel.

1% agarose of plasmid check using digestion reaction. Gel runned at 100V for 1 hour. Of all samples 10 μL was loaded with 2 μL loadingbuffer. 5 μL was loaded of marker

Transformation

The ligation mixes were incubated overnight. We transformed 10 μL of these ligations in Top10 competent cells, and these were grown on LB-plates with antibiotic over night.

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] where placed in front of GFP and measured over 18 hours using a Gen5 fluorenscence and absorbance plate reader 26 07 2010 Rbs.png

Strength was calculated by taking the mean of the ratio between the expression of known RBS ([http://partsregistry.org/Part:BBa_B0032 B0032]) and expression of Anderson RBS over some time. Expression being the measured fluorescence divided by measured biomass (absorbance, OD).

The measurements where taken from the part of the curve where optimal growth can be assumed, so from 0:40 until 2:30

RBS Strength
[http://partsregistry.org/Part:BBa_J61100 J61100] 0.047513
[http://partsregistry.org/Part:BBa_J61101 J61101] 0.119831
[http://partsregistry.org/Part:BBa_J61107 J61107] 0.065454
[http://partsregistry.org/Part:BBa_J61117 J61117] 0.038518
[http://partsregistry.org/Part:BBa_J61127 J61127] 0.087334
[http://partsregistry.org/Part:BBa_B0032 B0032] 0.300000

Next step: We want to relate the RBS sequence to the strength, so it might be possible to say predict something about the other Anderson RBS sequences.
