  • 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.

  • 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

  • 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 the fluid without IPTG to one and the fluid with IPTG to the other one.
  • 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 IPTG.

  • We examine a bacteria fluid drop from of each tube with our fluorescence microscopy.
  • 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 and without IPTG beam fluorescence;
  • Several bacteria with PLac-cI-GFP plasmid with IPTG beam fluorescence.
  • After 3 hours we measured the OD value of each tubes and it is 1.4.
  • Bacteria are too concentrate, thus we dilute them.
  • We take 2ml of LB medium, 1ml of bacteria fluid with and without IPTG and 2ul of kanamicin.
  • Examining with fluorescence microscopy and we saw that only bacteria with PLac-cI-GFP plasmid beame fluorescence.
