The present application includes systems and methods for identifying a compound capable of interacting with a G-Protein Coupled Receptor (GPCR) or Receptor Tyrosine Kinase (RTK) including providing a device capable of measuring cell-substrate impedance operably connected to an impedance analyzer, adding test cells expressing a GPCR or a RTK to wells of the device, measuring first impedances of the wells and optionally determining first cell indices from the first impedances, adding a compound to at least one well containing test cells to form at least one compound well and adding a vehicle control to at least another well containing test cells to form at least one control well, measuring second impedances of the compound well and the control well and optionally determining second cell indices from the second impedances, determining the change in the impedance or cell index for the compound well and the one control well, comparing the change in impedance or cell index between the compound well and the control well, and identifying the compound interacts with the GPCR or RTK if the comparison demonstrates a significant difference between the change in impedance or cell index of the compound well and the control well.
