Measurement
Fluorescence measurement
Material
- LB
- MQ water
- Micro-centrifuge
- 96-well microplate
- 50ml Falcon Tube
- Tecan Infinite m200 microplate reader
- PBS solution
Procedures
- Inoculate strains for overnight culture in 5mL LB
- Measure the OD600 of the overnight culture with 200uL of sample
- Dilute OD600 to 0.05 in 5mL of LB in 15mL tube
- Incubate at 30C for 4 hours so that bacteria reaches mid-log phase
- Dilute OD600 to 0.05 in 10mL of LB in 50mL tube
- Take 400uL of samples from culture media at one hour intervals starting from T=1hr
- Centrifuge at 15000rpm for 3 minutes
- Discard supernatant and resuspend pellet with 400uL PBS
- Take 150uL of sample and load onto microplate
- Measure OD600 and fluorescence intensity
