Methods of assessing cytolysis of cancer cells, including providing a cell-substrate impedance monitoring device operably connected to an impedance analyzer, wherein the device comprises a well for receiving cells and an electrode array at a base of the well; adding target cells characterized as cancer cells to the well; adding effector cells to the well to form a test well, wherein the effector cells are immune cells obtained or derived from a same patient as the target cells; monitoring cell-substrate impedance of the test well before and after adding the effector cells and optionally deriving an impedance-based parameter from the impedance; and determining effectiveness of effector cell killing of the target cells by comparing the impedance or impedance based parameter over time. |
