What Is SS-31?
SS-31, also known as Elamipretide, is a four-amino-acid Szeto-Schiller peptide with alternating aromatic and cationic residues. That structure lets it cross membranes and concentrate in the inner mitochondrial membrane, where it binds cardiolipin, the signature phospholipid of the mitochondrial cristae. Our SS-31 10mg vial contains the sequence D-Arg-Dmt-Lys-Phe-NH2, with a molecular weight of approximately 639.8 Da.
Because it acts directly at the membrane rather than through a cell-surface receptor, SS-31 is a widely used tool compound in bioenergetics research. Our SS-31 mitochondrial research guide summarises the published literature in more depth.
SS-31 Research Areas
Laboratory studies of SS-31 cover several areas:
Cardiolipin and Cristae Structure
SS-31 is used to study how cardiolipin binding affects cristae architecture, electron-transport-chain supercomplex stability and cytochrome c interactions. Published work can be explored on PubMed.
Oxidative Stress Models
Cell and tissue models use the peptide to investigate mitochondrial reactive oxygen species, lipid peroxidation and membrane-potential maintenance under stress.
Ischaemia–Reperfusion Research
Preclinical cardiac and renal models examine SS-31 in the context of reperfusion injury and mitochondrial permeability transition.
Ageing and Bioenergetics
SS-31 is investigated in models of age-related mitochondrial decline, muscle bioenergetics and neurodegeneration.
SS-31 vs MOTS-c
Both are studied in mitochondrial research but by different mechanisms. SS-31 acts at the membrane level by binding cardiolipin; MOTS-c is a mitochondrial-encoded signalling peptide that regulates AMPK and nuclear gene expression. Researchers frequently run the two in parallel to compare membrane-level and signalling-level approaches.
