SS-31 25mg (elamipretide) is a cell-permeable, mitochondria-targeting tetrapeptide supplied by Peptide Sciences for research into mitochondrial function and oxidative stress.
SS-31 and Mitochondrial Research
SS-31 (D-Arg-Dmt-Lys-Phe-NH2) accumulates in the inner mitochondrial membrane, where it binds cardiolipin, a phospholipid essential for the electron transport chain. Preclinical studies show it can stabilise cristae structure, reduce reactive oxygen species and improve ATP production in models of ageing, ischaemia and mitochondrial myopathy. It is a benchmark compound in mitochondrial-medicine research.
