Molecular Details
Usage & Storage
Description
Mitochondria-targeted tetrapeptide (elamipretide) that binds cardiolipin. Studied in mitochondrial-bioenergetics, ischaemia-reperfusion, and oxidative-stress research.
- Cell-permeable aromatic-cationic tetrapeptide
- Binds cardiolipin in the inner mitochondrial membrane
- Studied in electron-transport-chain efficiency research
- Investigated in ischaemia-reperfusion and oxidative-stress models
- Research Grade purity >=98%
SS-31 (elamipretide, MTP-131) is a synthetic aromatic-cationic tetrapeptide — D-Arg-Dmt-Lys-Phe-NH2, identified by CAS number 736992-21-5 — designed to concentrate in the inner mitochondrial membrane. Its alternating aromatic and cationic residues make it cell-permeable without a transporter, and the D-arginine and 2,6-dimethyltyrosine substitutions resist peptidase degradation. Unlike compounds that depend on membrane potential to accumulate, SS-31 associates selectively with cardiolipin, the signature phospholipid of the inner mitochondrial membrane, and preclinical research has characterised the consequences of that association: stabilised cristae architecture, improved electron-transport-chain coupling, and reduced peroxidase activity of cardiolipin-bound cytochrome c. Research has examined these effects in ischaemia-reperfusion, heart-failure, skeletal-muscle-ageing, and renal-injury models. SS-31 is supplied as a lyophilised white powder with a molecular weight of 639.79 Da and molecular formula C32H49N9O5. Supplied strictly for in-vitro laboratory research. Not for human or veterinary consumption.
Frequently Asked Questions
Is SS-31 legal to buy in Australia?
SS-31 is supplied strictly as a research chemical for in-vitro laboratory use. It is not approved for human therapeutic use in Australia and is not for human or animal consumption. Researchers are responsible for compliance with Therapeutic Goods Administration (TGA) regulations and their institution's protocols.
Is SS-31 third-party tested?
Yes. SS-31 is independently tested by Ozcanium Analytics, an independent Australian laboratory, at 98.89% purity by UPLC-MS/MS, analysed 7 September 2026 on lot 04/09/2026, net content 9.85 mg, verification code OZ-HPLCMS-TP96; bacterial endotoxin below 15.0 EU per vial by kinetic chromogenic LAL, analysed 8 September 2026, verification code OZ-ENDOTX-TEP4. The certificates are published in full on this page, and each verification code can be redeemed in the laboratory's own portal, so the document is confirmed against their records rather than ours.
What purity is SS-31?
SS-31 is independently tested by Ozcanium Analytics at 98.89% purity by UPLC-MS/MS, analysed 7 September 2026. That is the laboratory's measurement of the lot it tested, not a figure of ours: Tested Peptides runs no analysis of its own.
Is there a Certificate of Analysis (COA) for SS-31?
Yes. The SS-31 Certificate of Analysis is issued by Ozcanium Analytics, an independent Australian laboratory, and published in full at testedpeptides.com.au/certificates/ss-31. Testing is commissioned per compound and repeated periodically, and the current certificate replaces the last, so it is the most recent independent result for SS-31 rather than a test of every lot.
Where can I buy SS-31 in Australia?
SS-31 can be ordered here from Tested Peptides for in-vitro research use, dispatched same day from within Australia.
Do you provide dosing or administration guidance for SS-31?
No. As these compounds are supplied for laboratory research only, we do not provide dosing or administration protocols. Our research library covers reconstitution and concentration calculations for in-vitro work.
