MEASUREMENT

K176026([[1]]) is a device which can response to different concentrations of AHL. Here, we use K176126 as a detector to examing the AHL concentrations produced by constitutive promoters + luxI.

constitutive promoters + luxI-LVA: 
                                                                K176020( J23101->luxI-LVA);

plot

Figure 1- the relationship chart between FLU and OD600 of diffrent constitutive promoters + luxI-LVA

Figure 2- The time response of K176126 to different constitutive promoters + luxI-LVA. We can see from the figure that the more strong the constitutive promoter is , the more strong response it shows.

protocol

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 1:100 into 3ml fresh medium and grown for 3hrs.

5. 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) every 30 minutes in the next 4hrs.
