SS-31 – High Purity Mitochondria-Targeted Peptide
SS-31, part of the Szeto-Schiller peptides class, is a potent mitochondrial-targeting peptide known for its role in protecting cells from oxidative damage. At Elite Edge Biotech, we offer SS-31 in 5mg vials with ≥99% purity for research institutions studying mitochondrial function, aging, and neurodegeneration.
What Are Szeto-Schiller Peptides?
Szeto-Schiller peptides, named after researchers Hazel Szeto and Peter Schiller, are small peptides engineered to selectively target and enter the inner mitochondrial membrane. SS-31 (also known as Szeto-Schiller 31) is the most widely researched compound in this class.
Its design allows it to localize inside mitochondria, where it can interact with cardiolipin and reduce the harmful effects of oxidative stress, energy loss, and mitochondrial dysfunction.
How SS-31 Works
SS-31 is a mitochondria-targeted peptide that binds to cardiolipin, a unique phospholipid found in the inner mitochondrial membrane. This interaction helps:
- Maintain mitochondrial structure
- Prevent cell apoptosis caused by oxidative stress
- Improve ATP (energy) production efficiency
- Reduce inflammation and free radical damage
These effects make SS-31 valuable in research surrounding neurodegenerative diseases, cardiomyopathy, aging, and metabolic disorders.

FAQs
Q: What are Szeto-Schiller peptides used for in research?
A: They are studied for their ability to protect mitochondria from dysfunction, reduce oxidative stress, and improve cellular energy efficiency.
Q: What makes SS-31 unique as a mitochondrial targeting peptide?
A: SS-31 is small, lipophilic, and designed to pass through membranes easily. It selectively binds to cardiolipin, a key lipid in the mitochondrial inner membrane, giving it high specificity.
Q: Is SS-31 peptide legal to buy for research?
A: Yes, SS-31 is available for sale for research use only. It is not approved for human or veterinary use.
Q: Is SS-31 the same as Szeto-Schiller 31?
A: Yes. Szeto-Schiller 31 is the full name of SS-31, the most studied peptide of the Szeto-Schiller family.
