Experimental Methodology

For the assemblies constructuion we addopted the following method:

We used the pSB1C3 vector from the Biobrick BBa_J04450. Using this biobrick we added a red/white selection, where the red colonies are those which do not have the assembly, and the white ones are the correct ones.

See our Protocol

Assemblies forms

Assembly form template

This is the template designed to help with the laboratory organization during the assemble of biological parts. If you want to use the assembly method we used you can print the form and complete it for each construction. Hope it helps :)

30/06 PCR lasR (BBa_C0079). The purpose of this PCR was to add the RBS (BBa_K143021), through addition of the sequence in the primer foward, and also to remove the LVA tag. In our primers we only added the restriction sites X and S, so we still need to put it in the pSB1C3 for the Biobrick standard completion. When standardized this part will be called BBa_K1521001.	01/07 Gel Purification of lasR PCR product	02/07 Transformation of the Biobricks: BBa_143012 BBa_K081001 BBa_E0840 Inoculum of the Biobricks sent by iGEM HQ: BBa_K316037 BBa_K316018 BBa_K316015	03/07 Transformation of the Biobricks sent by the Imperial College Team: BBa_K316016 BBa_K143031 Miniprep, Quantification of the plasmidial DNA samples and Restriction Analysis: BBa_143012 BBa_K081001 BBa_E0840	04/07	05/07	06/07 Inoculum: BBa_143012 BBa_K081001 BBa_E0840

We also added the RBS (BBa_K143021) using the foward primer. In our primers we only added the restriction sites X and S, so we still need to put it in the pSB1C3 for the Biobrick standard completion. When standardized this biobrick will be called BBa_K1521000.

28/07 Assembly AIII: Restriction analysis (+NdeI enzyme) OBS: This analysis was reapeted because we had problems confirming the assembly. The issue was that both the construction and the pSB1C3 vector had similar size. Assembly AII, AV and AVI: Digestion EXSP	29/07 >Assembly AII, AV and AVI: Gel Purification Ligation	30/07 >Assembly AII, AV and AVI: Transformation	31/07 Assembly AII, AV and AVI: Inoculum PCR BBa_K143055 for RBS removal OBS: This was one of the parts sent by the Imperial College Team. Because of a comunication failure we assumed that this part was comming without the RBS, so we included a RBS in the parts we were going to use with this Lac promotor :) PCR of Plac BBa_K143055 was followed by a Gel Purification and Ligation in the PUC19 vector
