protocols
aTc,AHLHybrid promoter: BBa_K176070, BBa_K176071, BBa_K176075, BBa_K176078:
1. Streak a plate of the strain which contain one of the parts listed in pSB1A3 .
2. Inoculate two 3ml cultures of supplemented M9 Medium and antibiotic(Ampicillin 0.1mg/ml) with single colony from the plate.
3. Cultures were grown in test tubes(BIO BASIC INC.12ml Polypropylene Round-bottom Culture Tubes With Graduations And Dual Cap Cat.No:TD444) for 16hrs at 37℃ with shaking at 200rpm..
4. Cultures were diluted 1:1000 to 11 tubes 3ml fresh medium and grown for 4.5hrs.
5. Stock concentration of the cognate AHL, 3-oxohexanoyl-homoserine and aTc (anhydrotetracycline) are diluted and added to different tube to get different final concentration listed in the table below:
Tube No. | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 |
c(AHL)/M | 0 | 1.00E-06 | 1.00E-06 | 1.00E-06 | 1.00E-06 | 1.00E-06 | 1.00E-04 | 1.00E-04 | 1.00E-04 | 1.00E-04 | 1.00E-04 |

To ensure the same response time , the AHL and aTc should be added with a time interval of 2mins between tubes, so do the measurements procedure.
7. Measure the fluorescence(SHIMDZU SPECTROFLUOROPHOTOMETER RF-5301PC, 250ul quartz cell path length 10mm,501 nm excitation,514 nm emission,1.5nm slit width) and absorbance ((HITACHI UV-VIS spectrophotometer U-2810 ,200ul quartz cell path length 10mm,600nm,1.5 nm slit width) for the first time 30 minutes after adding AHL and aTc. Repeat measurement several hours a time until OD600 reach to 0.8,it will take about 7hours in average.
