SS-31

SS-31 is a Szeto-Schiller Tetrapeptide supplied for laboratory research. Mitochondria-targeted tetrapeptide studied in vitro for oxidative phosphorylation modeling, mitochondrial membrane potential analysis, and cardioprotective pathway research.

Yes — SS-31 is the research designation for the mitochondria-targeted tetrapeptide also known as elamipretide (and MTP-131). It is studied for its association with the inner-mitochondrial-membrane lipid cardiolipin and oxidative phosphorylation.

SS-31 is supplied as a lyophilized (freeze-dried) powder — a dehydrated form that keeps the peptide stable during shipping and storage. In the laboratory it is reconstituted (returned to liquid form) using a solvent such as bacteriostatic water, added slowly against the side of the vial, which is then swirled gently — never shaken — until the powder fully dissolves. All handling is for in vitro research use only.

Store the lyophilized SS-31 powder at -20°C, protected from light and moisture, where it remains stable long-term. Once reconstituted, keep it refrigerated (2-8°C) and use it within the timeframe appropriate for your research protocol.

Every batch of SS-31 is produced to a purity of 99% or higher. Purity and molecular identity are verified using standard analytical methods — high-performance liquid chromatography (HPLC) to measure purity, and mass spectrometry (MS) to confirm the peptide's molecular weight.
