RBS measurement parts
Experimental setup
The following RBS sequences from the Anderson RBS family were used:
For the purpose of comparison and standardization the following RBS was used as a reference for our characterization.
These RBS sequences were positioned upstream of the standard GFP coding sequence, in order to be able to measure expression.
Cloning method
This is a summary of the cloning methods that succeeded. For more information on the exact methods and all attempts made see what was done under the header 'Characterization of RBS sequences' in our blog posts starting around 6 July
The Anderson Constructs
BBa_I13401 was PCR amplified by using the universal primers G00100 and G00101. The purified PCR product was back-digested using XbaI and PstI. The Anderson RBSs are provided in pSB1A2 plasmids. These were digested using SpeI and PstI and ligated with the digested I13401 insert. Transformation into competent TOP10 E.coli cells yielded positives, as determined by UV-light plate analysis.
The Reference Construct
BBa_J23100, which is contained in the pSB1A2 plasmid was digested using SpeI and PstI. BBa_E0240 was digested using XbaI and PstI and ligated with the digest product of J23100. Transformation into E.coli TOP10 yielded positives as determined by UV-light.
The BioBricks
The Biobricks generated for the measurements were: K398500, K398501, K398502, K398503, K398504 and K173000. A general example map of the construction is shown below, where the RBS is displayed in fucsia. Notice the additional XbaI site located between the promoter and RBS sequence. This site is inherent to the Anderson RBS inserts on the distribution plates and was maintained in our constructs in case promoter swapping would be necessary in future.
