  • This testing part, the Test Sensing Prey Construct, is representing the sensitivity of the prey cell towards the prey molecule (AHL)
  • This part allows us to quantise the activation of gene expression by different concentrations of AHL and is used to assay AHL
  • This testing part allows us to investigate three parameters:
    • How different AHL levels activate genes at a constant LuxR expression (The transfer function of pLuxR)
    • How much AHL is present, by referring to the transfer function
    • How LuxR levels effect gene activation
