SS-31 Research Peptide
SS-31, also referenced as elamipretide, is a mitochondria-targeted tetrapeptide studied for its interaction with cardiolipin on the inner mitochondrial membrane. Here is the research context and what accompanies each lot.

Research context
SS-31 belongs to the Szeto–Schiller family of small peptides characterized by an alternating aromatic–cationic motif. That motif is associated with accumulation at the inner mitochondrial membrane independent of membrane potential, which is what makes the series interesting to mitochondrial researchers.
Published work focuses on its association with cardiolipin and downstream effects on electron transport chain organization and reactive oxygen species handling in model systems. Findings are preclinical.

Frequently asked questions
- What is SS-31?
- A mitochondria-targeted tetrapeptide, also referenced as elamipretide, studied preclinically for its association with cardiolipin on the inner mitochondrial membrane.
- Is SS-31 the same as elamipretide?
- The names refer to the same research peptide; SS-31 is the Szeto–Schiller designation and elamipretide is the assigned nonproprietary name.
- What testing does your SS-31 carry?
- Third-party HPLC purity and mass spectrometry identity for the exact lot, linked to the batch number on the vial.
