How SS-31 Works

SS-31 is a cell-permeable, aromatic-cationic tetrapeptide that selectively targets the inner mitochondrial membrane. For researchers looking to buy SS-31 peptide, our product acts by binding directly to cardiolipin—a unique polyglycerol phospholipid essential for structural cristae organization—after penetrating cells independent of mitochondrial membrane potential.
