-We searched more information about lab safety.
-We utilized literature to prepare our experiment of the InterLab Measurement Study.

-This week we made electrocompetent cells. Their transformation efficiency is higher than that of chemocompetent cells, so they could be useful in making biobricks and transforming our assembled gBlocks.
-We repeated the tail PCR of luxR. This time we performed a touchdown PCR in order to become more specific results.
-Our three biobricks were purified by using a gel extraction kit. After this, we inserted our biobricks in pSB1C3. The next step is screening colonies by PCR to find plasmids with the right insert.
-We made our devices for the InterLab Measurement Study by using the Biobrick Assembly Method. After this we transformed electrocompetent E. cloni with our devices. First we grew our cells under the recommended conditions of iGEM on plates and afterwards we made a liquid culture. On Friday, we made our standard curve based on fluorescein and we measured our devices.
-We used the NEBuilder® HiFi DNA Assembly Master Mix to assemble our gBlocks. After doing a PCR, we visualised our results on a gel. We obtained a positive result for gBlocks 5 and 6. So we transformed these assembled gBlocks in electrocompetent E. cloni. We checked our transformed gBlocks on PCR, but a confirmation by restriction mapping is still needed.

-The transformation of chemocompetent cells for the Interlab Measurement Study was not efficient, therefore we repeat this with electrocompetent cells. We grew the transformed cells overnight and performed a miniprep.
-To check if the operon of ΔTarΔCheZ is OK, we used a PCR to confirm that all the genes are present.
-After performing a PCR, there were no bands visible of the assembled gBlocks, probably we didn’t use enough Gibson Assembly Master Mix
-We started making three BioBricks starting from our gBlocks. We performed a high fidelity tail PCR to include the prefix and suffix in our biobrick. The parts were digested and purified on a gel.
-We ordered materials for leucine and AHL detection

-Perform gel electrophoresis to confirm double knock-outs: 2 colonies of ΔTar ΔCheZ and 4 colonies of ΔTar ΔTsr still had ΔTar. This means we have our double mutants! We still need to check ΔTar ΔCheZ to be sure the rest of the operon is still intact.
-We performed a motility test to verify the phenotypical change of knocking out CheZ
-Assembly of gBlocks by using the Gibson Assembly Method
-We decided to participate at the iGEM 2015 Measurement Interlab Study. Therefore we transformed E. cloni with the biobricks J23101, I12504, J23106 and J23117.
