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 [http://partsregistry.org/Part:BBa_I763019 I763019] plasmid.
2. In tube C we add 5ml of LB medium and a colony of [http://partsregistry.org/Part:BBa_I763031 I763031] 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 [http://partsregistry.org/Part:BBa_I763019 I763019] plasmid doesn’t beam fluorescence with (A2, B2) nor without (A1, B1) IPTG;
8. Very few bacteria with [http://partsregistry.org/Part:BBa_I7630231 I763031] plasmid with (C2) and without (C1) IPTG beam fluorescence.
  • In conclusion, we see that bacteria with [http://partsregistry.org/Part:BBa_I763019 I763019] plasmid (tubes A1, B1, A2, B2) don't seem to work at all, and bacteria with [http://partsregistry.org/Part:BBa_I763031 I763031] plasmid (tube C1, C2) don't seem to work properly either. We plan other experiments for next week.
