How Long Does SS-31 Last? Shelf Life & Stability
"Stable" is meaningless without saying stable against what. SS-31 has its own set of degradation routes, and they determine which storage precautions actually matter for it.
Overview
Robust. Its main practical quirk is sticking to surfaces, not chemical breakdown.
What SS-31 actually is
A tiny four-part peptide that homes in on the powerhouse of the cell, sticking to a lipid (cardiolipin) found only in the inner mitochondrial membrane. Studied around cellular energy, oxidative stress, and aging. Also called Elamipretide.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Degradation routes specific to SS-31
- Adsorptive loss to plasticware from the cationic charge — the main practical concern.
- Slow C-terminal amide hydrolysis over long storage.
The D-arginine and dimethyltyrosine residues make it resistant to proteolysis and racemisation, so it is one of the more solution-stable peptides in the catalogue.
Freeze–thaw tolerance
Tolerant; the unnatural residues resist degradation. Aliquot as standard practice.
How storage addresses these routes
Practical window once reconstituted: 3-4 weeks at 2-8 °C.
Full SS-31 storage conditionsWhat SS-31 is studied for
Studied for selective association with cardiolipin in the inner mitochondrial membrane, the basis of its mitochondrial targeting.
Examined for effects on mitochondrial energy production in research models of mitochondrial dysfunction.
