1. Growth O/N for 15h in LB (5ml) of:

      - trasformed E.Coli with appropriate antibiotic;

      - E. Coli.

2. All misure has to be done in M9 at OD=1.

3. The day after in the morning OD measure.

4. To obtain OD=1:

     -centrifugate 4ml of  bacteria culture at 4400rpm for 3min at 25°C;
     -eliminate the supernatant;
     -risuspende the pellet with 6ml in M9 medium with glucose with appropriate antibiotic    
       (1000x).

5. OD measure: adjust OD to 1 through further diluition or growth.

6. Adjust PMT offset with untrasformed E.Coli.

7. Fluorescence test of the culture before IPTG induction.

8. IPTG induction:

            -centrifugate bacteria culture at 4400rpm for 3min at 25°C;
      -eliminate the supernatant;
      -risuspende the pellet in M9 medium and 2mM IPTG with appropiate antibiotic (1000X);

9. Incubate at 37°C.

     10. Fluorescence test after10min, 20min, 30min, 1h, 2h.
