Often written SS31, SS 31, elamipretide, Bendavia or MTP-131, it is a mitochondria-targeted tetrapeptide studied for cardiolipin binding and electron-transport efficiency.\u003c\/p\u003e\n\u003cp\u003eSS-31 is a synthetic tetrapeptide from the Szeto-Schiller family of mitochondria-targeted peptides, first described in the early 2000s by pharmacologists Hazel Szeto and Peter Schiller. Its sequence is D-arginine, 2',6'-dimethyltyrosine, lysine and phenylalanine with an amidated C-terminus, usually written D-Arg-Dmt-Lys-Phe-NH2. The alternating pattern of positively charged and aromatic residues lets it cross cell membranes and accumulate many hundred-fold in the inner mitochondrial membrane. It is better known in clinical literature as elamipretide, was developed under the codes MTP-131 and Bendavia, and is written online as SS31, SS-31 peptide or SS 31.\u003c\/p\u003e\n\u003cp\u003eSS-31 is studied for the protection of mitochondrial structure and function in models of heart failure, skeletal muscle weakness and ageing, in genetic mitochondrial disease, and in ischaemia-reperfusion injury of the heart, kidney and brain. Its mechanism is unusual for a peptide: rather than binding a receptor, it binds cardiolipin, the signature phospholipid of the inner mitochondrial membrane, stabilising the cristae and the respiratory chain complexes that depend on it and reducing the leak of reactive oxygen species.\u003c\/p\u003e\n\u003cp\u003eOmega Peptides Australia supplies SS-31 as a high-purity (≥99% HPLC), COA-verified lyophilised powder in a 10mg research vial.

In stressed or aged mitochondria cardiolipin is oxidised and lost, cytochrome c changes into a peroxidase that oxidises even more cardiolipin, and the electron transport chain becomes leaky and inefficient. SS-31 binds cardiolipin through electrostatic attraction between its two positive charges and the phospholipid head groups, and through insertion of its aromatic side chains into the membrane. This binding restrains the peroxidase activity of cytochrome c, restores the ordered structure of the membrane and improves the efficiency of electron flow.\u003c\/p\u003e\n\u003cp\u003eThe result in experimental systems is higher ATP output for the same oxygen consumption, less superoxide and hydrogen peroxide production, and preservation of cristae architecture. SS-31 is not a conventional free-radical scavenger; it prevents the generation of oxidants at the source. Like most small unmodified peptides it has a short circulating half-life and is cleared quickly, so research protocols rely on repeated exposure. It is often paired with MOTS-c, which acts through metabolic signalling rather than membrane stabilisation, and with NAD+, which supplies the electron carrier the respiratory chain depends on.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompound\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSS-31\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAlso known as\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eElamipretide, MTP-131, Bendavia, SS31, SS-31 peptide, D-Arg-Dmt-Lys-Phe-NH2, SS 31\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCAS number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e736992-21-5 (free base)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMolecular formula\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eC32H49N9O5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMolecular weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eApproximately 639.8 g\/mol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSequence\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eD-Arg-Dmt-Lys-Phe-NH2 (Dmt is 2',6'-dimethyltyrosine)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMitochondrial research\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePurity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e≥99% HPLC, batch COA supplied\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eForm\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLyophilised powder in a sealed sterile vial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVial sizes available\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e10mg — $79.99\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStorage (lyophilised)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2–8°C short term or −20°C long term, protect from light and moisture, avoid repeated freeze-thaw\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStorage (reconstituted)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2–8°C, use within 28 days\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eReconstitution\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBacteriostatic water (recommended)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\u003ch2\u003eAvailable sizes and pricing\u003c\/h2\u003e\n\u003cp\u003eSS-31 is supplied in a single 10mg research vial.
