SS-31, also known as elamipretide or MTP-131, is a synthetic aromatic-cationic tetrapeptide studied for interactions with cardiolipin-containing mitochondrial membranes and mitochondrial bioenergetics. It is supplied as a lyophilised research material.
Research material only
This material is not supplied as a medicine, treatment, supplement or consumer product. It is not for human or veterinary use, consumption or administration, and is not intended to diagnose, treat, cure or prevent any disease.
Compound overview
Research context
Published mechanistic studies have examined SS-31 in model and mitochondrial membranes, including its partitioning at charged membrane interfaces, effects on membrane surface electrostatics and interactions associated with cardiolipin. Other studies have investigated the cytochrome c–cardiolipin complex, mitochondrial respiration and the mitochondrial protein-interaction landscape.
These findings describe the materials, models and conditions used by the cited researchers. They do not establish the identity, purity, performance or suitability of the material supplied on this page.
Batch documentation
Independent analytical documentation is published where available for specific batches and variations. A result indicator appears only when a published record is available. Match the product, stated mass and batch identifier to the corresponding report before relying on any result.

Supply and laboratory handling
- Supplied as a lyophilised research material.
- Keep the sealed lyophilised vial dry and protected from direct light.
- A cool, dry place, refrigerator or freezer may be used according to the intended storage duration and your laboratory’s validated procedure.
- Use clean laboratory technique and equipment appropriate to the intended analytical method.
- Follow the lot-specific documentation and your laboratory’s validated handling and storage procedures.
- Avoid repeated temperature cycling and unnecessary exposure to moisture.
Where a batch document or supplier specification gives different instructions, the lot-specific document takes precedence.
