Revision as of 15:10, 4 October 2007
- 09/17/07
- Ligations for:
-[http://partsregistry.org/Part:BBa_I763026 I763026] + [http://partsregistry.org/Part:BBa_I763019 I763019];
-[http://partsregistry.org/Part:BBa_I763026 I763026] + [http://partsregistry.org/Part:BBa_I763004 I763004];
-[http://partsregistry.org/Part:BBa_I763025 I763025] + [http://partsregistry.org/Part:BBa_J04031 J04031].
- We transform ligations and strake them on plates.
- 09/18/07
- We inoculate a colony for yesterday ligations in 5ml of LB medium O/N.
- 09/19/07
- Miniprep for:
-[http://partsregistry.org/Part:BBa_I763028 I763028];
-Ptet-LacI-T-PLac-GFP;
-Ptet-LacI-GFP(Spe/Pst1), (Xba/Pst1).
- Digestion for:
-[http://partsregistry.org/Part:BBa_I763028 I763028] with Eco/Spe;
-Ptet-LacI-T-PLac-GFP with Eco/Spe;
-Ptet-LacI-GFP with Eco/Spe;
-[http://partsregistry.org/Part:BBa_I763007 I763007] with Eco/Xba;
-Plac-cI-LacY with Eco/Spe1;
- Band extraction from gel for all digestion and then we observe:
-[http://partsregistry.org/Part:BBa_I763028 I763028], Ptet-LacI-T-PLac-GFP are died;
-Ptet-LacI-GFP is correct;
-[http://partsregistry.org/Part:BBa_I763007 I763007] not found;
-Plac-CI-LacY is correct.

Testing our devices
We wanted to test if our newly-constructed devices work, that is if they beam fluorescence when inducted with IPTG. To do so we performed 3 tests in parallel in 3 different tubes, that we name here A, B and C.
- 1. In tube A e in tube B we add 5ml of LB medium and 2 different colonies of I763019 plasmid.
- 2. In tube C we add 5ml of LB medium and a colony of PLac-cI-GFP plasmid.
- 3. After 2 hours we measure the OD value of tubes A, B, C and it is around 0.5.
- 4. For tubes A, B, C we divided the bacteria fluid in two different tubes A1, A2; B1, B2; C1, C2.
- 5. We add 1mM IPTG to the solution into tubes A2, B2, C2.
- The analyzed fluid without IPTG (tubes A1, B1, C1) includes:
- -2.5ml of original tube fluid;
- --2.5ml of LB medium;
- -2.5ul of kanamicin.
- The analyzed fluid with IPTG (tube A2, B2, C2) includes:
- -2.5ml of original tube fluid;
- -2.5ml of LB medium;
- -2.5ul of kanamicin;
-50ul of 100mM IPTG.
- 6. We examine a bacteria fluid drop of tubes A1, A2, B1, B2, C1, C2 with our fluorescence microscope.
- 7. The bacteria with I763019 plasmid doesn’t beam fluorescence with (A2, B2) nor without (A1, B1) IPTG;
- 8. Very few bacteria with PLac-cI-GFP plasmid with (C2) and without (C1) IPTG beam fluorescence.
- In conclusion, we see that bacteria with I763019 plasmid (tubes A1, B1, A2, B2) don't seem to work at all, and bacteria with PLac-cI-GFP plasmid (tube C1, C2) don't seem to work properly either. We plan other experiments for next week.
