SS-31 - 10 mg

Updated Ouralus research desk

Synthetic tetrapeptide

A synthetic aromatic-cationic tetrapeptide, D-Arg-2,6-dimethylTyr-Lys-Phe-NH2, whose alternating charged and aromatic residues associate with cardiolipin at the inner mitochondrial membrane. Examined in the literature in the context of bilayer electrostatics and structure-activity mapping.

Characterization

What it is, stated plainly.

What it is

A synthetic tetrapeptide, D-Arg-Dmt-Lys-Phe-NH2, with an alternating aromatic–cationic residue motif. It associates with cardiolipin in the inner mitochondrial membrane through a combination of electrostatic attraction to the anionic head group and hydrophobic insertion of the aromatic side chains. Published work is structure–activity and interaction mapping; it sits in the mitochondrial-bioenergetics literature.

How a lot is verified

Purity assayed by third-party and net content (mg per vial) measured by the lab, with a certificate of analysis published where a report exists.

Handling & storage

Supplied as a lyophilized powder. Store at −20°C, desiccated and protected from light. Handled per the receiving laboratory's procedures. Not for human consumption.

Questions

Answered straight.

What is SS-31?

SS-31 is a synthetic tetrapeptide with the sequence D-Arg-Dmt-Lys-Phe-NH2, where Dmt is the non-standard residue 2,6-dimethyltyrosine. It is also known as elamipretide, MTP-131, and Bendavia. Ouralus supplies it as a lyophilized powder for laboratory research use only.

What is the molecular formula of SS-31?

C32H49N9O5 (molar mass ≈ 639.8 g/mol; PubChem CID 11764719, CAS 736992-21-5, UNII 87GWG91S09). The alternating aromatic and basic residues, and the C-terminal amide, are what distinguish it from a conventional linear tetrapeptide.

Who can order?

These materials are supplied strictly for laboratory and research use, to purchasers of legal age. They are not supplements, drugs, or foods, and are not for human or animal consumption.

Is SS-31 legal to buy?

SS-31 is supplied strictly as a research chemical for laboratory research use only — it is not a drug, supplement, or food, and not for human or animal consumption. It ships to purchasers of legal age for research use. Buyers are responsible for compliance with the laws that apply to research materials in their own jurisdiction.

Is a certificate of analysis provided with SS-31?

Yes — the current lot of SS-31 has a third-party HPLC certificate of analysis from Janoshik, independently verifiable by lot (verify key XLC46CAH4U1N). The current lot assayed 99.717%. We publish the certificate before making any purity claim; this is a research chemical for laboratory use only.
