Research Context
SS-31 is studied in mitochondrial biology, where the literature focuses on its affinity for cardiolipin in the inner mitochondrial membrane. Its alternating aromatic-cationic motif is the structural feature most often cited. Ascend Research supplies SS-31 strictly as a laboratory reference material; no representation is made regarding any physiological outcome, and it is not supplied for use in humans or animals.
Handling and Reconstitution
Allow the vial to reach room temperature before opening. Reconstitute with sterile water and swirl gently. Store the lyophilised powder dry at 2–8°C, refrigerate reconstituted material and use within 30 days. Avoid repeated freeze–thaw cycles.
What's Included
- One lyophilised vial (10mg)
- Protective packaging
Frequently Asked Questions
What is the CAS number for SS-31?
736992-21-5 for the free base. The acetate salt carries CAS 1334953-95-5.
Is SS-31 the same as elamipretide?
Yes — SS-31, elamipretide, MTP-131 and Szeto-Schiller peptide all refer to the same compound.
How many amino acids does SS-31 contain?
Four — it is a tetrapeptide.
Why does SS-31 target mitochondria?
The literature attributes this to its affinity for cardiolipin, a phospholipid concentrated in the inner mitochondrial membrane.
How is SS-31 stored?
Dry at 2–8°C. Refrigerate after reconstitution and use within 30 days.
Where does Ascend Research ship from?
