Shipping information01 / The compound
Cardiolipin, membrane biology & mitochondrial energetics
SS-31, also known as elamipretide and historically as MTP-131, is a synthetic four-residue peptide developed for mitochondrial research. It belongs to the Szeto-Schiller class of aromatic-cationic peptides and has been investigated for its ability to associate with the inner mitochondrial membrane.
A major focus of SS-31 research is its interaction with cardiolipin, a phospholipid concentrated in the inner mitochondrial membrane and closely involved in membrane structure, respiratory-chain organization and mitochondrial bioenergetics. Modern research describes SS-31's activity more broadly than its earlier characterization as a simple mitochondrial antioxidant.
02 / Research profile
Its aromatic-cationic structure has been studied in cardiolipin-containing membrane systems. The proposed mechanisms encompass lipid organization, membrane-surface electrostatics and mitochondrial bioenergetics, extending beyond an antioxidant-only description.
SS-31 has been investigated for its interaction with cardiolipin and cardiolipin-containing mitochondrial membrane systems. Experimental studies using membrane models and isolated mitochondria have examined how these interactions relate to mitochondrial membrane organization and bioenergetic processes.
Preclinical and biochemical research has examined SS-31 in relation to the cytochrome c/cardiolipin complex, mitochondrial electron transport and ATP synthesis. These studies provide mechanistic context for how SS-31 interacts with mitochondrial bioenergetic systems under controlled experimental conditions.
Biophysical research has examined SS-31 binding to lipid bilayers and its effects on membrane-surface electrostatics. These findings have expanded the proposed mechanism beyond a simple antioxidant model and toward interactions involving membrane charge, lipid organization and cardiolipin-associated mitochondrial processes.
Reading the evidence
These findings come from biochemical, biophysical, cellular and animal experimental systems and should be interpreted within the specific models and conditions used in each study.

05 / Storage & handling
Keep sealed research material protected from moisture, unnecessary light and temperature fluctuations. Use the storage conditions documented for the specific compound, formulation and lot.
Solution stability depends on solvent, concentration, container and experimental conditions. Use a validated laboratory protocol; a universal post-reconstitution shelf life is not established by the literature summaries.
