SS-31 — compound background
Mitochondria-targeting aromatic-cationic tetrapeptide (cardiolipin-binding)
SS-31 (Elamipretide) is a Szeto-Schiller aromatic-cationic tetrapeptide (D-Arg-2',6'-dimethyltyrosine-Lys-Phe-NH2) that concentrates in the inner mitochondrial membrane and binds cardiolipin, the lipid unique to that membrane. Its structure is the reason it is studied specifically at the mitochondrion rather than as a general antioxidant.
Solubility & reconstitution
Freely water-soluble owing to its cationic character; dissolves quickly and cleanly. Use low-bind labware, since the strong positive charge promotes adsorption to surfaces.
Commonly worked at 1-5 mg/mL.
Storage
Sealed powder stable at -20 °C. Refrigerate at 2-8 °C.
Commonly worked with for 3-4 weeks at 2-8 °C.
Stability
The D-arginine and dimethyltyrosine residues make it resistant to proteolysis and racemisation, so it is one of the more solution-stable peptides in the catalogue.
Reading the Certificate of Analysis
Confirm the mass near 639.8 Da and check stereochemistry — the D-residue and the dimethyltyrosine are essential, so diastereomer or des-methyl impurities are the characteristic things to look for.
