Research applications
SS-31 (elamipretide) is a cell-permeable, mitochondria-targeted tetrapeptide of the Szeto-Schiller family that selectively binds cardiolipin on the inner mitochondrial membrane. It is studied in mitochondrial bioenergetics and ROS research, ischemia-reperfusion injury models, and cardiolipin-cytochrome c interaction studies.
