  • Problems:
    • Fluorescence was saturated for our positive control
  • Conclusions:
    • Fluorescence for the shifted sample (SS) shows increase of fluorescence overtime indicating that the temperature sensitive promoter (pLambda cI) is activated when shifted to 37°C
    • However we could not determined whether the shifted sample reached the fluorescence level of the positive control as fluorescence readings were saturated on the fluorometer.
  • The non shifted sample (kept at 28°C) was constant at fluorescence levels similar to the blanks. This suggests that the promoter repression is tight at 28°C.
  • Blanks were constant
