SS-31

SS-31, also designated elamipretide, is a synthetic mitochondria-targeting tetrapeptide employed as a research tool for examining inner-membrane organization and bioenergetics. It selectively concentrates at the inner mitochondrial membrane through affinity for the phospholipid cardiolipin. Investigators use SS-31 to probe structural and functional aspects of mitochondria in controlled laboratory systems. The compound is supplied exclusively for in-vitro and experimental research applications.

Research centers on SS-31 binding to cardiolipin, a phospholipid essential for assembling electron-transport-chain supercomplexes and maintaining cristae architecture. This interaction is studied for its capacity to influence membrane curvature and the spatial arrangement of respiratory complexes under oxidative challenge. Experimental work examines how the peptide association may support electron-transfer efficiency and limit peroxidation of cardiolipin itself. These mechanistic investigations are conducted in isolated mitochondria and cultured-cell preparations.

SS-31 is applied in laboratory models of mitochondrial dysfunction, oxidative stress, aging-related bioenergetic decline, and ischemic injury. Studies focus on parameters such as ATP generation capacity, reactive-oxygen-species handling, and overall cellular energy resilience. Researchers employ the peptide to evaluate preservation of cristae morphology and electron-transport efficiency when mitochondria are subjected to controlled stressors. All work remains confined to in-vitro systems and non-clinical experimental platforms.

Published laboratory investigations document that SS-31 associates with cardiolipin and is observed to support maintenance of cristae structure in stressed mitochondrial preparations. Experimental readouts frequently include oxygen-consumption rates, ATP synthesis measurements, and markers of membrane integrity. Findings consistently position the peptide as a useful probe for cardiolipin-dependent bioenergetic processes. These observations derive solely from model systems and do not extend beyond research contexts.

SS-31 is intended strictly for in-vitro and laboratory research use and is not for human or animal consumption. Standard peptide-handling practices apply, including appropriate storage conditions and reconstitution in compatible aqueous buffers for mitochondrial assays. Investigators should verify solubility and stability under the specific experimental conditions employed. All applications remain limited to investigative studies of mitochondrial structure and function.
