What Is SS-31 Peptide?

Laboratories working within cellular & longevity research can access SS-31 Peptide as a research-grade compound for pre-clinical and in vitro applications. SS-31 Peptide is a mitochondria-targeted tetrapeptide. Researchers apply it in laboratory and in vitro research settings. We follow a defined synthesis standard throughout production. Consequently, we limit distribution to qualified researchers only.

Research Applications

SS-31 is a small, cell-permeable tetrapeptide. It alternates cationic and aromatic residues to concentrate at the inner mitochondrial membrane, a targeting mechanism that sets it apart from other antioxidant compounds.

Pre-clinical literature discusses this compound within the broader field of cellular & longevity research. Here, researchers examine receptor interactions, signalling pathways, and structure-activity relationships. A well-characterised reference compound helps a laboratory keep experimental conditions consistent from one run to the next. However, results can still shift depending on reconstitution method, storage conditions, and assay design. For this reason, we encourage researchers to follow standard protocols and log batch numbers for traceability.

Purity, Testing & Quality Assurance

An independent third-party laboratory tests each batch, confirming purity and identity via HPLC or mass spectrometry. We provide a Certificate of Analysis on request. This lets a research group verify a batch before use, supporting reproducibility when comparing results against other laboratories. We also retain records for every production run, so researchers can match a specific COA back to the vial received.

Storage & Reconstitution

As with most lyophilised research peptides, researchers should reconstitute this compound immediately before use with an appropriate solvent such as bacteriostatic water. Reconstituted solutions lose stability more quickly at room temperature, so we recommend refrigeration and prompt use. Researchers generally benefit from reconstituting smaller volumes as needed rather than a full batch at once, since repeated freeze-thaw cycles can compromise the compound. Prior to reconstitution, the lyophilised powder itself stays comparatively stable when stored per the COA.

Usage Restrictions

This product serves laboratory and in vitro research only. It is not a medicine, and researchers must not use it for human consumption, animal consumption, diagnosis, or therapy. For independent chemical reference data, researchers can consult the PubChem compound database.
