SS-31 (50mg vials)

Description

SS-31 is a small synthetic peptide of the Szeto-Schiller family, built around the four-residue sequence D-Arg-Dmt-Lys-Phe-NH₂. Its structure incorporates the non-standard residue 2′,6′-dimethyltyrosine (Dmt), and the molecule carries a net positive charge with an approximate molecular weight near 640 Da. These features are central to why the peptide is studied as a tool for reaching the mitochondrial compartment of the cell.

Research interest in SS-31 centers on its tendency to concentrate within the inner mitochondrial membrane, where it is reported to associate with cardiolipin, a phospholipid closely tied to the organization of the electron transport chain. Investigators use the peptide to probe how this interaction relates to membrane structure, mitochondrial bioenergetics, and redox processes in cell-based and biochemical model systems.

Because it combines selective subcellular localization with a compact, well-defined sequence, SS-31 is frequently treated as a reference compound in studies of compartment-targeted peptide delivery and in broader mitochondrial peptide chemistry.
