SS-31 is a synthetic mitochondria-targeted peptide (also known as elamipretide) designed to selectively localize to the inner mitochondrial membrane. It is a short tetrapeptide that readily penetrates cells and concentrates in mitochondria due to its unique aromatic-cationic structure. SS-31 has been widely studied in biochemical and cellular research for its ability to interact with cardiolipin, a phospholipid essential for maintaining mitochondrial membrane integrity and optimal electron transport chain function.
In laboratory studies, SS-31 has been investigated for its potential to support mitochondrial bioenergetics, stabilize mitochondrial structure, and reduce the production of reactive oxygen species (ROS). By helping preserve mitochondrial function under stress conditions, it has become a useful tool in experimental models examining oxidative stress, metabolic activity, aging processes, and mitochondrial dysfunction. Researchers commonly utilize SS-31 in in-vitro cell culture systems and in-vivo experimental models to explore mitochondrial protection mechanisms and energy metabolism.
Due to its ability to cross cellular membranes and accumulate in mitochondria, SS-31 is frequently used in research involving cardiovascular biology, neuromuscular studies, metabolic research, and investigations into mitochondrial-related cellular pathways.
