The transfer function describes how the output [[PoPS]] varies with the input concentration of the AHL molecule.  A representative transfer function is shown above.  Transfer curves for members of the family have been measured using fluorescence output that we expect is proportional to [[PoPS]] output.  Experiments are planned to measure the [[PoPS]] levels directly for members of the device family.  The parameters of interest that can be derived from the transfer curve are the input and output Hi/Lo values and the switch point of the device.  Transfer curves for the specific members of the device family can be found on their individual data sheets.  Transfer functions should also indicate the level of variation that can be expected in a genetically identical population of cells carrying the device.
