Abstract: A screening system provided with a potential-dependent Na ion channel that extends the duration of the action potential associated with depolarization, and a K ion channel that deepens the resting membrane potential in the negative direction, said screening system furthermore including cells provided with ion channels that contribute to deepening the resting membrane potential in the negative direction and/or shortening the duration of the action potential as target ion channels. By such cells, the action of a test compound on the target ion channel can be easily evaluated by providing an inhibitor for the K ion channel to control the probability of cell death.

Abstract: An object of the present invention is to provide a screening system that targets ion channels and has superior efficiency. The present invention provides a material for screening for compounds that act on a target ion channel, comprising cells which retain at least one first DNA encoding a voltage-dependent Na ion channel that has been inhibited from being inactivated, and in which a K ion channel has been activated so that a resting membrane potential becomes deeper in a negative direction.
