What it is
SS-31, referred to in much of the literature as elamipretide, is a synthetic tetrapeptide built on an alternating aromatic-cationic sequence. That arrangement is what allows it to cross cell membranes without a dedicated transporter and to concentrate in the inner mitochondrial membrane, where it associates with the phospholipid cardiolipin rather than distributing evenly through the cell.
It ships as a lyophilised powder in a sealed glass vial, supplied in 10 mg and 50 mg presentations. Each lot carries a Certificate of Analysis documenting compound identity and purity. Supplied as a laboratory reference material for research use only, and not for human or veterinary use.
What the research explores
Because it localises to one specific membrane compartment, SS-31 is widely used as a mitochondrial-targeting probe. Published research examines:
- The binding interaction with cardiolipin in the inner mitochondrial membrane
- Cristae architecture and membrane curvature in isolated mitochondria and cell models
- Electron transport chain organisation and respiratory supercomplex stability
- Reactive oxygen species generation measured in mitochondrial preparations
- Uptake and subcellular distribution of aromatic-cationic peptides
These are areas of active laboratory investigation reported in the scientific literature. Elements DNA makes no representation about therapeutic effect and supplies this compound for in vitro and preclinical research only.
Questions
How should the vial be stored?
Keep the sealed vial cool, dry and out of direct light before opening. Once reconstituted, store refrigerated and treat the solution as short-lived. Avoid repeated freeze-thaw cycles, which degrade peptide integrity.
How is the lyophilised powder reconstituted?
Solvent is normally added slowly down the inside wall of the vial and dissolved by gentle swirling rather than shaking. Solvent, working concentration and protocol are determined by the researcher. We do not provide dosing or administration guidance.
Is SS-31 the same compound as elamipretide?
Yes. SS-31 and elamipretide are two names for the same aromatic-cationic tetrapeptide, and both appear across the published mitochondrial research literature. The material is supplied here as a laboratory reference compound only.
What arrives in the shipment?
One sealed glass vial of lyophilised powder in the size selected, protectively packaged and labelled with its batch identifier. Solvent and laboratory consumables are not included.
Which lot is SS-31's published certificate for?
Lot 1500-501, measured 99.40% by HPLC, tested Jul 22, 2026, by Pacific Coast Biologics Inc. The full certificate, including the laboratory's own assay rows, is published at /coa/64ZVFVAGTK.
