Mitochondrial Peptide
SS-31 is a tetrapeptide that selectively targets the inner mitochondrial membrane, referenced in in-vitro mitochondrial research. 10mg lyophilized powder.
What is SS-31 (Elamipretide)?
SS-31 is a tetrapeptide that selectively targets the inner mitochondrial membrane, referenced in in-vitro mitochondrial research. 10mg lyophilized powder. Independently third-party tested to 99%+ purity. For in-vitro laboratory research use only. Not for human consumption.
SS-31 is a synthetic aromatic-cationic tetrapeptide (D-Arg-Dmt-Lys-Phe-NH2) that localizes to the inner mitochondrial membrane. Each vial from Genetic Peptides USA is manufactured for in-vitro and laboratory research and is shipped from within the USA.
SS-31 is studied in mitochondrial research for its interaction with cardiolipin, electron transport chain efficiency, and reactive oxygen species in cell and animal models. The information on this page summarizes published scientific context for educational purposes and is not a claim of any therapeutic effect.
Every batch of SS-31 is independently third-party tested using HPLC (high-performance liquid chromatography) for purity and mass spectrometry (MS) for identity confirmation. Where a Certificate of Analysis is available for the current lot, it is displayed on this page. Researchers should verify the lot number on the vial against the COA for their records.
SS-31 is supplied as a lyophilized (freeze-dried) powder, the most stable form for shipping and storage. Store unopened vials cool, dry and away from light; refrigeration at 2–8°C or freezing at -20°C is standard laboratory practice for long-term storage. Once reconstituted with a suitable solvent such as bacteriostatic water, keep refrigerated and follow your institution's handling protocols.
SS-31 is a water-soluble tetrapeptide with alternating aromatic and cationic residues. This structure lets it pass through cell membranes and gather at the inner mitochondrial membrane. Researchers often pair it with mitochondrial readouts such as oxygen-consumption assays, membrane-potential dyes and ROS probes, and compare it with other mitochondria-focused compounds such as MOTS-c and NAD+.
Where can I buy SS-31 in the USA? Genetic Peptides USA ships SS-31 research vials from within the United States with tracking on every order.
Is SS-31 third-party tested? Yes. Batches are tested by an independent laboratory using HPLC/MS for purity and identity.
What form is SS-31 supplied in? A lyophilized powder in a sealed vial, intended for reconstitution in a laboratory setting only.
Research Use Only: SS-31 is sold strictly for laboratory research use only. It is not for human or animal consumption, not a drug, food, or cosmetic, and is not intended to diagnose, treat, cure, or prevent any disease. Purchaser assumes responsibility for proper handling in accordance with applicable laws.
