About SS-31 Elamipretide

SS-31, also known as elamipretide, is a small mitochondria-directed tetrapeptide with the sequence D-Arg-Dmt-Lys-Phe-NH2, in which the dimethyltyrosine (Dmt) residue confers antioxidant character and membrane affinity. Its unusual D-amino-acid composition resists conventional proteolysis and supports selective uptake by mitochondria in cell-based experiments. Researchers employ SS-31 to explore cardiolipin remodeling, electron-transport-chain function, reactive-oxygen-species generation, and mitochondrial morphology under metabolic or ischemic stress conditions. The molecule has become a standard tool in mitochondrial research because it links physical membrane interactions to measurable bioenergetic outcomes. Purity demands are exacting: diastereomeric contamination, incomplete amidation, or residual coupling reagents can alter membrane localization and confound oxygen-consumption measurements. Shandong Shengyuan manufactures SS-31 under documented processes and releases each batch only after RP-HPLC purity of 99.8% or higher, LC-MS identity confirmation, and impurity profiling. Lyophilized product is supplied for research use only; not for human or veterinary use.
