Dry lab results

Using our software tools we have evolved a pool of candidate expression adaptors from which we have picked six sequences (BBa_K528015 to BBa_K528020)with variable expression levels and synthesized them. This way we have obtained expression adaptors on pSB1C3. All adaptors are under BBa_J23102 promoter in order to measure their strength acording to Synthetic Biology standards.


The adaptors have following predicted strengths according to RBSDesigner software:

Wet lab results

So far we have managed to obtain only BBa_K528021 (BBa_K528018+YFP measurement device) as working part. We have characterized it using fluorimetry in order to see how accurate are RBSCalculator predictions for the BBa_K528018 adaptor. We have obtained following results:

Part NameDescriptionExpression level as %B0034+GFPStd Dev.
BBa_K528021BBa_K528018+YFP measurement device20,37%3,21%
referenceBba_J23102+B0034+GFP (100% reference construct)100,00%2,61%

As you can see prediction is quite accurate. Clonning of other fluorescent proteins and testing the rest of expression adaptors is still to be done.
