What customers say
Research overview
SS-31, also known as elamipretide, is a synthetic tetrapeptide composed of D-arginine, 2′,6′-dimethyltyrosine (Dmt), lysine, and phenylalanine, developed by Hazel Szeto and Peter Schiller as part of the broader Szeto-Schiller peptide series.
Research Overview The peptide's defining characteristic in research is its ability to concentrate selectively within the inner mitochondrial membrane, driven by electrostatic interaction between its cationic residues and cardiolipin, a phospholipid found almost exclusively in that membrane. This targeting mechanism has made it a widely used tool in mitochondrial research, examined across models of oxidative stress, cardiac tissue, and age-related mitochondrial dysfunction, without requiring a conventional peptide targeting sequence.

Frequently asked questions
Is a Certificate of Analysis included?+
Yes. Every order ships with a third-party CoA matched to the lot number printed on your cartridge. A sample CoA is available on the site.
How is purity verified?+
Each batch is HPLC-tested for purity and mass-spec confirmed for identity, then tested for heavy metals, residual solvents and endotoxins.
Does the solution need reconstituting?+
No. The cartridge is supplied as a ready-to-use liquid solution in 3ml bacteriostatic water.
How is it shipped and stored?+
Validated temperature-controlled packaging, UK next-day dispatch. Store at 2–8°C on arrival, do not freeze, 12-month shelf life.
Who is this supplied to?+
Qualified personnel for in vitro laboratory research and analytical work only. Not for human or animal consumption.
