Overview
SS‑31 (also known as Elamipretide or MTP‑131) is a synthetic tetrapeptide widely utilized in in vitro and laboratory‑based research involving mitochondrial structure, bioenergetics, and oxidative‑stress response pathways. It is of particular interest for studies examining peptide interactions with cardiolipin, a phospholipid located within the inner mitochondrial membrane, and its role in mitochondrial stability and function.
