What is SS-31?
SS-31 is a synthetic four-amino-acid peptide with the sequence D-Arg-Dmt-Lys-Phe-NH2. Dmt is 2′,6′-dimethyltyrosine, a modified tyrosine. It has the formula C32H49N9O5, weighs about 639.8 g/mol and carries CAS number 736992-21-5.
The design alternates charge and ring: positive, aromatic, positive, aromatic. That pattern, plus its small size, lets it cross membranes. It’s drawn to cardiolipin, a lipid found almost only in the inner mitochondrial membrane, which is why it’s called mitochondria-targeted.

What researchers study SS-31 for
SS-31 has been studied in mitochondrial disease models and in clinical trials under a drug name. The research-grade peptide here is for lab use only. See NIH PubChem.
How to store SS-31
Store refrigerated at 36 to 46 °F (2 to 8 °C). It’s stable when kept cold and sealed. It dissolves in water.
Most labs reconstitute with Research Water, which is sterile-filtered water with 0.9% benzyl alcohol.
When it’s time to reconstitute, let the vial come to room temperature first. Add the solvent slowly down the inside wall of the vial so it doesn’t hit the powder directly, then swirl gently until the liquid is clear. Don’t shake it. Write the date on the label so you know how long it’s been mixed.
