Sensor Experiment 1: Receivers vs AHL

Day 1 - Preparation

1. From transformation plate, pick up a small quantity of cells from a colony using sterilized toothpick and streak on LA plate with the appropriate antibiotic resistance. Incubate at 37 degrees Celsius for 8+ hr.

2. From the streak plate, choose a single-cell colony and pick up cells using sterilized toothpick, then inoculate 5ml LB culture medium to which the appropriate antibiotic resistance (50mg/l) has been added. Incubate overnight at 37 degrees Celsius in a shaking incubator.

Day 2 - Measurement

1. Transfer 1ml of the overnight culture into 30ml fresh LB culture medium. Incubate in shaking incubator at 37 degrees.

2. Measure OD of culture every hour or so, until OD reaches fixed value (culture at full growth).

3. Transfer culture into 50ml ultracentrifuge tube and spin at 8000rpm for 5 minutes.

4. Resuspend pellet with 30ml fresh LB culture.

5. Incubate culture in shaking incubator at 30 degree Celcius for 10 minutes.

6. Transfer 1ml of culture into microcentrifuge tube and put on ice. Immediately add AHL to rest of culture to attain desired concentration. (Note: Between the steps detailed below, samples should be kept on ice to minimize cellular activity.)

7. Obtain OD600 of 2x diluted sample by transferring 500ul of sample into cuvette, adding 500ul MiliQ water and measuring the resulting OD.

8. Ultracentrifuge remaining 500ul of sample at 13000rpm for 2min, discard supernatant, then resuspend pellet with 1ml MiliQ water.

9. Ultracentrifuge sample again at 13000rpm for 2min, discard supernatant and resuspend with precisely 1ml MiliQ water (this results in 2x dilution).

10. Measure GFP fluorescence with a fluorimeter at 488nm excitation, 513nm emission.

11. Every hour, sample 1ml of culture and repeat steps 7-10 until fluorescence reaches steady state.

Sensor Experiment 2: Senders vs Receivers

Day 1 - Preparation

1. From transformation plate, pick up a small quantity of cells from a colony using sterilized toothpick and streak on LA plate with the appropriate antibiotic resistance. Incubate at 37 degrees Celsius for 8+ hr.

2. From the streak plate, choose a single-cell colony and pick up cells using sterilized toothpick, then inoculate 5ml LB culture medium to which the appropriate antibiotic resistance (50mg/l) has been added. Incubate overnight at 37 degrees Celsius in a shaking incubator.

Day 2 - Mix & Culture

1. Prepare microcentrifuge tubes (3 samples for each sender-receiver pair). Add 400ul of LB-Amp culture medium to each microcentrifuge tube.

2. Transfer 1ml of each overnight culture to separate microcentrifuge tubes and ultracentrifuge at 12000rpm for 1min. Discard supernatant and resuspend cells with 1ml LB-Amp. Repeat with remaining overnight culture if necessary to obtain the required amount of cell culture.

3. For sender-receiver test: Add 50ul each of sender and receiver cultures to a microcentrifuge tube prepared in step 1. For the negative control (receiver only), add 100ul of receiver culture only.

4. Incubate microcentrifuge tubes at 37 degrees Celsius overnight.

Day 3 - Observation & Measurement

1. Wash cells by ultracentrifuging at 13000rpm for 2min, discarding supernatant and resuspending cells with MiliQ water. Repeat, and resuspend with precisely 1ml MiliQ water.

2. For direct observation, bring cells suspended in water to darkened room and shine with UV Black Light. GFP fluorescence should be observable if sufficiently strong promoter activation has been achieved.

3. Measure GFP fluorescence with a fluorimeter at 488nm excitation, 513nm emission.
