SS-31 Mitochondrial Peptide (Elamipretide): Mechanism, 5 Research Areas & Trusted UK Supply
When a targeted SS-31 mitochondrial peptide draws attention in ageing research, muscle performance, cardiac studies, and oxidative stress models, the real question is always mechanism. SS-31 (also known as Elamipretide) stands out for its precise interaction with mitochondrial membranes, which is exactly why labs across the UK keep the SS-31 peptide on their shelf.
What is the SS-31 Mitochondrial Peptide?
The SS-31 mitochondrial peptide, commonly referred to in literature as Elamipretide, is a synthetic tetrapeptide designed for mitochondrial targeting. It belongs to the Szeto-Schiller peptide family and is studied primarily for its affinity to cardiolipin in the inner mitochondrial membrane. With a molecular weight of roughly 639.8 Da and the sequence D-Arg-2′,6′-dimethyl-Tyr-Lys-Phe-NH₂, SS-31 is one of the most characterised mitochondria-targeting compounds available.
Why Mitochondrial Targeting Matters
Mitochondria are the powerhouses of the cell, responsible for ATP production and redox balance. High-energy-demand tissues (skeletal muscle, heart, brain, kidneys) are especially sensitive to mitochondrial dysfunction. The SS-31 mitochondrial peptide is investigated as a tool to explore these pathways without acting as a broad, non-specific antioxidant.
Mechanism of Action: Cardiolipin & Mitochondrial Function
SS-31 binds selectively to cardiolipin, helping stabilise mitochondrial cristae structure, support electron transport chain efficiency, reduce excess ROS production, and promote healthy ATP output. Unlike general antioxidants, the action of this SS-31 peptide is membrane-specific — which is the feature that first made Elamipretide interesting to mitochondrial biologists.

5 Current Research Areas for SS-31 / Elamipretide
1. Ageing & Muscle Function
Studies explore the SS-31 mitochondrial peptide for its potential in sarcopenia, endurance, and age-related mitochondrial decline. Late-life administration has shown promise in restoring aspects of mitochondrial performance in preclinical models.
2. Cardiac Research
High-energy tissue like the heart is a frequent focus area for mitochondrial protection studies involving SS-31, including models of heart failure and ischaemia-reperfusion injury.
3. Renal Research
Kidney injury and ischaemia models are another active strand of SS-31 peptide investigation, again tied to its cardiolipin-stabilising mechanism.
4. Neurodegenerative Models
Interest exists in bioenergetic support for neuronal health and other oxidative stress-related models where mitochondrial dysfunction is implicated.
5. Clinical-Stage Mitochondrial Disorders
Clinical-stage investigations of Elamipretide have included primary mitochondrial myopathy and Barth syndrome, underlining why the SS-31 mitochondrial peptide remains a reference compound in the field.

Common Questions About the SS-31 Peptide
Is SS-31 the same as Elamipretide?
Yes — SS-31 is the research designation; Elamipretide (also called Bendavia) is the name used in clinical studies. They refer to the same SS-31 mitochondrial peptide.
Who uses SS-31 in research?
Primarily academic and private labs studying mitochondrial biology, ageing, metabolic health, cardio-renal models, and related fields.
What purity should an SS-31 peptide be?
Look for ≥99% HPLC purity with mass-spec identity confirmation and a published Certificate of Analysis. Our SS-31 is supplied at ≥99% purity.
How should SS-31 be stored?
Lyophilised SS-31 is stable at room temperature for short transit. For long-term storage keep at −20°C; once reconstituted, store at 2–8°C and use promptly.
