LuxR from AraC and TetR(Faifan)

- measured Absorbance of the overnight culture at 660 nm = 1.5

- diluted 60 ul culture into 5.40 ml Tsy+KAN. Absorbance at 660 nm = 0.035

- incubated 37 degree Celsius for 2.5 hrs, Absorbance at 600 nm = 0.7

- diluted 1 ml culture into 5 ml Tsy+Kan, OD@600nm = 0.165

- set up 96 well plate reader experiment:

  • added dH2O to final the volume to 200 ul
  • added 40 ul of mineral oil to each well to protect evaporation
  • set the machine to run 24 hrs, read every 10 mins
