Description

SS-31 – 10mg

Research Grade Peptide

SS-31 (Szeto-Schiller peptide 31) is a synthetic aromatic-cationic tetrapeptide, sequence D-Arg-2′,6′-dimethyltyrosine-Lys-Phe-NH2, supplied as a lyophilized powder for use in laboratory protocols. It is referenced in the scientific literature as a mitochondria-targeted reference compound.

Structurally, SS-31 carries an alternating aromatic-cationic motif that allows the molecule to cross cell membranes and concentrate in the inner mitochondrial membrane, where its defining, well-characterized property is a selective association with the phospholipid cardiolipin. These points describe the molecule’s chemical characteristics as reported in the research literature, not any physiological effect in humans.

Manufactured by Fit Aminos to research-grade standards and intended strictly for laboratory and scientific research purposes.
