Abstract: Methods for identifying compounds that modulate cellular responses stimulated by IgE, which include providing an impedance-based system that monitors cell-substrate impedance of cells on a substrate; introducing cells to the substrate of the system; adding at least one test compound and IgE to the cells, wherein the at least one test compound is suspected of modulating cell responses stimulated by the IgE; adding an antigen to the cells; monitoring the cell-substrate impedance of cells on the substrate; and analyzing the cell-substrate impedance to evaluate whether the at least one test compound alters a cellular response to stimulation with the IgE.

Abstract: Methods of identifying whether a biologically active agent affects an oncogene addicted pathway within a cancer cell, by introducing a biologically active agent suspected of affecting an oncogene addicted pathway to a first well and a negative control to a second well, and introducing a stimulating agent that stimulates the oncogene addicted pathway to both wells; monitoring cell-substrate impedance of the two wells and optionally determining cell indices from impedance values; generating an impedance based curve for each of the two wells from the impedance values or from the cell indices; comparing the impedance-based curves to determine a degree of similarity; and if significantly different concluding the biologically active agent affects the oncogene addicted pathway within the cancer cells.
