- 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.
