SS-31 is a laboratory research peptide used to study mitochondrial membrane interactions, cardiolipin binding, and cellular signaling pathways in controlled experimental systems. This product is supplied strictly for research use only. It is not approved or intended for human or animal use, and any discussion of biological activity refers only to preclinical or in vitro research.
One of the unique aspects of SS-31 is its specific affinity for cardiolipin, a phospholipid located within the inner mitochondrial membrane that is essential for maintaining electron transport chain structure and membrane integrity. Disturbances in cardiolipin stability are commonly examined in research involving oxidative stress, mitochondrial dysfunction, and bioenergetic decline. SS-31’s ability to interact with cardiolipin has therefore made it a recurring subject in studies investigating how mitochondrial membrane condition affects broader cellular behavior.
Additionally, research has documented that SS-31 may influence the production of reactive oxygen species (ROS) at the mitochondrial level. Excessive ROS production is commonly evaluated in studies on cellular stress, inflammation, and mitochondrial impairment. By focusing on mitochondria directly, rather than acting as a broad-spectrum antioxidant, SS-31 offers researchers a pathway to study targeted mechanisms of oxidative modulation rather than systemic antioxidant activity.
For laboratory use, SS-31 is commonly supplied as a high-purity, LPS-free peptide, manufactured to meet strict research standards. As an endotoxin-free peptide, it is frequently utilized in sensitive in vitro and ex vivo experimental setups where contamination control is critical. Research peptides such as SS-31 are typically endotoxin tested to support reproducibility and reliability across mitochondrial and cellular research applications.
This compound is intended strictly for research use only and is not approved for human or animal use.

Storage Instructions:
All of our products are manufactured using the Lyophilization (Freeze Drying) process, which ensures that our products remain 100% stable for shipping for up to 3-4 months.
Once the peptides are reconstituted (mixed with bacteriostatic water), they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.
Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure. This causes the water in the peptide vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure known as lyophilized peptide. The puffy white powder can be stored at room temperature until you’re ready to reconstitute it with bacteriostatic water.
Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used immediately, or in the next several days, weeks or months, short-term refrigeration under 4C (39F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.
However, for longer term storage (several months to years) it is more preferable to store peptides in a freezer at -80C (-112F). When storing peptides for months or even years, freezing is optimal in order to preserve the peptide’s stability.
