• 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.

• We inoculate a colony for yesterday ligations in 5ml of LB medium O/N.

• 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 want to test if our newly-constructed devices work, that is if they beam flourescence when inducted with IPTG.

• In 2 different tubes we add 5ml of LB medium and 2 different colonies of [http://partsregistry.org/Part:BBa_I763019 I763019] plasmid.
• In another tube we add 5ml of LB medium and a colony of PLac-cI-GFP plasmid.
• After 2 hours we measure the OD value and it is around 0.5.
• For each original tube we divide the bacteria fluid in two different tubes.
• We add 1mM IPTG to the solution into one tube.

• The analyzed fluid without IPTG includes:

-2.5ml of original tube fluid,

-2.5ml of LB medium,

-2.5ul of kanamicin.

• The analyzed fluid with IPTG includes:

-2.5ml of original tube fluid,

-2.5ml of LB medium,

-2.5ul of kanamicin,

-50ul of 100mM IPTG.

• We examine a bacteria fluid drop from of each tube with our fluorescence microscope.
• The bacteria with [http://partsregistry.org/Part:BBa_I763019 I763019] plasmid don’t beam fluorescence with and without IPTG;
• Very few bacteria with PLac-cI-GFP plasmid with and without IPTG beam fluorescence.

In conclusion, we see that bacteria with [http://partsregistry.org/Part:BBa_I763019 I763019] plasmid don't seem to work at all, and bacteria with PLac-cI-GFP plasmid don't seem to work properly.
