AHLHybrid promoter:BBa_K176026, BBa_K176126, BBa_K176128, BBa_K176130

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 tubes of 3ml fresh medium and grown for 4.5hrs.

5. Stock concentration of the cognate AHL, 3-oxohexanoyl-homoserine is diluted and added to different tubes to yield different final concentrations (1E-5,1E-7,1E-8,1E-9,1E-10M).To ensure the same response time , the AHL should be added with a time interval of 2mins between tubes, so do the measurements procedure.

6. 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. Repeat measurement every 30 mins in the next 4hrs.

MEARSUREMENT2

We test the response of the hybrid promoter( K176000) to both tetR and AHL. Here LuxR is ligated after J23107.
