pTet-LuxR-pLux-GFP construct in-vivo

• Aim: The aim of the test was to check if construct 1 of infector detector works in-vivo
• The protocols for the experiment can be found in the Protocols page *The results of the test showed that pTet-LuxR-pLux-GFPmut3b is working in vivo and GFPmut3b produced increases with increasing [AHL]

pTet-LuxR-pLux-GFP construct in-vitro

• Aim: The aim of the test was to check if construct 1 of infector detector works in-vitro, for a number of concentrations of AHL
• The results of the test seemed very variable and didn't seemed to comply with the tests that were carried out before. There was a lot of variability between the samples and 4nM of AHL seemed to have fluorescence output greater than 50nM.
• It was decided to carry out the experiment again. The reasons for the inaccuracies in the data could have been:
  • The reaction was not mixed properly or the right amounts were not pipetted
  • The plates had already been used and thus could have affected the reaction
