Its defining research feature is selective association with cardiolipin, a phospholipid unique to the inner mitochondrial membrane.\u003c\/p\u003e\n\u003cp\u003eBecause of that membrane-targeting behavior, SS-31 has become a widely used probe in mitochondrial-structure and bioenergetics research, with a literature base spanning cellular models through late-stage clinical-development publications. It is supplied here as high-purity lyophilized material strictly for qualified research use.\u003c\/p\u003e\n\u003ch2\u003eMechanism of Action — Research Overview\u003c\/h2\u003e\n\u003cp\u003eIn research models, SS-31 concentrates at the inner mitochondrial membrane, where it binds cardiolipin and is studied for its influence on cristae architecture, electron-transport-chain organization, and membrane-potential stability under stress conditions.\u003c\/p\u003e\n\u003cp\u003eStudies also examine its interaction with cytochrome c–cardiolipin binding and its effects on reactive-oxygen-species generation at the membrane level. Unlike broad antioxidants studied in research, SS-31's interest lies in its precise subcellular localization.\u003c\/p\u003e\n\u003ch2\u003eResearch Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMitochondrial membrane and cristae-architecture research\u003c\/li\u003e\n\u003cli\u003eCardiolipin-interaction and bioenergetics studies\u003c\/li\u003e\n\u003cli\u003eOxidative-stress response models\u003c\/li\u003e\n\u003cli\u003eIschemia-reperfusion research models\u003c\/li\u003e\n\u003cli\u003eCellular senescence and age-related mitochondrial-decline studies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSS-31 Specifications\u003c\/h2\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFormat\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLyophilized powder in sealed 3 mL glass vial (10mg)\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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eChemical 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\u003e≈ 639.8 g\/mol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePubChem CID\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e11764719\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSynonyms\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eElamipretide, MTP-131, Bendavia, D-Arg-Dmt-Lys-Phe-NH2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStorage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eStore lyophilized at −20°C, sealed, protected from light and moisture.
