07/17/07
  • We amplify some bio- bricks of interest for our project from the IGEM plates. We resuspend and transform:
    • J04430 to test the GFP fluorescence detection with our experimental set up;
    • J04431 to test the GFP (+LVA) half-life since we need a GFP with a short one for our project;
    • J04500, the PLac promoter inducible by IPTG;
    • J04631, the GFP (+LVA) protein.
  • We strake on plates with the right antibiotic.


07/18/07
  • We perform a test for GFP induction with IPTG. We pick a colony from the J04430 and J04431 plates and grow it in 5 ml of LB medium during the day. In the afternoon we diluite the 5 ml cultures in 50 ml and let them growing overnight.
  • We pick a colony from 07/17 plates, inoculate each in 5 ml of LB medium and incubate overnight.


07/19/07
  • In the morning we diluite the J04430 and J04431 cultures to an OD=0.05. We grow the cultures till an OD = 0.4 – 0.6. We add 1 mM IPTG to induce GFP expression and we test fluorescence after 2 h. (photos).
  • Althought J04431 works rigth in presence of IPTG, J04430 doesn't. So, we perform a run on electroforesis gel for the J04430 plasmid. We find that it doesn't match the rigth molecular weight. We think maybe there's something wrong with the plasmid.


07/20/07
  • Plasmid digestion (link):we digest J04500 with Spe1 and Pst1 and J04631 with Xba1 and Pst1.
  • We perform the gel extraction procedure and store at -20°C.
  • We amplify amd transform I13507 and R0051from the IGEM plate.
