Notebook

You should make use of the calendar feature on the wiki and start a lab notebook. This may be looked at by the judges to see how your work progressed throughout the summer. It is a very useful organizational tool as well.

Main Assembly Map

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 :)

Characterization Assemblies

Apart from the main genetic circuit we also assembled others for characterization purposes, such as the validation of the promoters and tunning of our threshold setter concentration, the QteE.

Promoter BBa_K823003

Question: Does the constitutive promoter BBa_K823003 work properly?

Results: After the incubation period of the transformed E. coli a large portion of the colonies were glowing green. So the promoter does work. Moreover, this biobrick works on E. coli despite the fact it was designed for B. subtilis.

Promoter BBa_K143015

Question: How does the transcription caused by this promoter varies with the IPTG induction?

Results:

Tunning of the QteE Threshold

Question:What are the concentration of QteE needed to hamper the LasR induction of the promoter PlasR?

This is the most difficult task of our project. Tunning the production of QteE so that we establish the correct threshold for the discretization of the Cystatin C level in serum. To attack this challenge we designed 3 circuits so that we could plot a calibration curve. In this circuits we put the transcription of the LasR and QteE under two differnt promoters, the Pveg (BBa_K823003) and PlasR (BBa_K143015).

  • 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 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 04/07 05/07 06/07
  • Inoculum:
    • BBa_143012
    • BBa_K081001
    • BBa_E0840
07/07 08/07 09/07
  • Inoculum:
    • BBa_B0015
 10/07
  • Miniprep, Quantification and Restriction Analysis:
    • BBa_B0015 (restriction analysis fail, repeat)
  • PCR the qteE gene for amplification. 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.
  • Ligation of RBS+lasR in PTZ57R/T vector (instaclone kit)
 11/07 12/07 13/07
14/07 15/07 16/07
  • Transformation:
    • BBa_K823003
    • RBS+qteE
  • Electrophoresis analysis:
    • BBa_B0015

21/07 22/07 23/07 24/07 25/07 26/07 27/07
28/07
  • Assembly AIII:
    • Restriction analysis (+NdeI enzyme)
    • OBS: This analysis was reapeted because we had problems confirming the assembly. The issue was that bot the construction and the pSB1C3 vector had similar size. Check out the Lab Journal report of the day for more information.
  • Assembly AII, AV and AVI:
 29/07 30/07 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
