New Biobricks Design

We want to test if the algorithm delivers functional locks and keys. In order to do that, we plan to characterize two locks and keys generated by our algorithm. The RBS’s chosen were the weak and medium (biobricks) from the registry. The DNA sequences of these new parts are:

These sequences will be incorporated as new biobricks to the registry and will be used to construct the next assemblies (figures 14 and 15).

In order to obtain confident data, we also design control biobricks. The construction of these controls is shown in figure 16 and figure 17.

Figure 16. Control for lock/key for “medium” ribosome binding site. The construction was made using the Biobricks [http://partsregistry.org/Part:BBa_R0010 R0010] and [http://partsregistry.org/Part:BBa_E0240 E0240] in a Cloranphenicol biobrick backbone [http://partsregistry.org/Part:pSB1C3 pSB1C3].

Figure 17. Control for lock/key for “weak” ribosome binding site. The construction was made using the Biobricks [http://partsregistry.org/Part:BBa_R0010 R0010], [http://partsregistry.org/Part:BBa_B0031 B0031] and [http://partsregistry.org/Part:BBa_J04630 J04630] in a Cloranphenicol biobrick backbone [http://partsregistry.org/Part:pSB1C3 pSB1C3].
