About SS-31

SS-31, also known as Elamipretide (MTP-131), is a synthetic aromatic-cationic tetrapeptide from the Szeto-Schiller peptide series designed to selectively target the inner mitochondrial membrane. For research teams studying mitochondrial bioenergetics and oxidative stress, it offers a well-characterized cell-permeable probe with a documented mechanism of cardiolipin association. Puritide Research supplies SS-31 as a high-purity, research-use-only material, synthesized for in vitro and animal-model work and backed by third-party-verified certificates of analysis so your data rests on consistent, documented quality.

What Is SS-31?

SS-31 (Elamipretide) is a synthetic cell-permeable tetrapeptide with the sequence D-Arg-Dmt-Lys-Phe-NH2, where Dmt denotes the non-natural residue 2',6'-dimethyltyrosine. Its alternating aromatic and basic residues give the molecule a net positive charge and, together with the C-terminal amide and D-arginine, reduce susceptibility to enzymatic degradation.

In experimental settings, SS-31 is used as a mitochondria-targeted probe. It is reported to accumulate at the inner mitochondrial membrane through energy-independent permeation and to associate with cardiolipin, a phospholipid central to mitochondrial cristae structure and electron-transport function.

Present understanding derives from in vitro assays, animal models, and ongoing research. Findings should be interpreted within their experimental context and not treated as established clinical outcomes. Puritide Research supplies SS-31 strictly for laboratory use; it is not approved here for human or veterinary application.
