- We amplify some bio-bricks of interest to our project from the IGEM plates. We re-suspend and transform:
- [http://partsregistry.org/Part:BBa_J04430 J04430] to test the GFP fluorescence detection with our experimental set-up;
- [http://partsregistry.org/Part:BBa_J04431 J04431] to test the GFP (+LVA) half-life since we need a GFP with a short one for our project;
- [http://partsregistry.org/Part:BBa_J04500 J04500], the PLac promoter inducible by IPTG;
- [http://partsregistry.org/Part:BBa_J04631 J04631], the GFP (+LVA) protein.
- We strake on plates with the right antibiotic.

- We perform a test for GFP induction with IPTG. We pick a colony from the [http://partsregistry.org/Part:BBa_J04430 J04430] and [http://partsregistry.org/Part:BBa_J04431 J04431] plates and grow it in 5ml of LB medium during the day. In the afternoon we dilute the 5 ml cultures in 50ml and let them grow overnight.
- We pick a colony from 07/17 plates, inoculate each one in 5ml of LB medium and incubate overnight.

- In the morning we grow the [http://partsregistry.org/Part:BBa_J04430 J04430] and [http://partsregistry.org/Part:BBa_J04431 J04431] cultures to an OD = 0.4 – 0.6. We add 1mM IPTG to induce GFP expression to test fluorescence after 2h. (photos).

- Plasmid digestion (link):we digest [http://partsregistry.org/Part:BBa_J04500 J04500] with Spe1 and Pst1 and [http://partsregistry.org/Part:BBa_J04631 J04631] with Xba1 and Pst1.
- We perform the gel extraction procedure and store at -20°C.
- We amplify [http://partsregistry.org/Part:BBa_I13507 I13507] and [http://partsregistry.org/Part:BBa_R0051 R0051]from the IGEM plates.
