METHOD OF ASSAYING SUBSTANCE CAPABLE OF CHANGING MITOCHONDRIAL MEMBRANE POTENTIAL

摘要

The present invention aims to provide a convenient and high precision evaluation method of a pharmaceutical agent that changes the mitochondrial membrane potential, using a mitochondrial membrane potential of a cultured cell as an index. The present invention provides a method for evaluating the ability of a test substance to change the mitochondrial membrane potential by using, as an index, the change in the mitochondrial membrane potential, which is produced by the addition of an ion permeability regulator on a cellular membrane to a cell culture medium, wherein the change is measured as variation in the fluorescent intensity of a fluorescent dye.
