SS-31 (Elamipretide): A Mitochondria-Targeting Peptide Research Guide
What is SS-31?
SS-31, also known as elamipretide, is a small synthetic tetrapeptide studied for its ability to concentrate within mitochondria — the energy-producing compartments of the cell. Unlike most peptides, which act at cell-surface receptors, SS-31 is investigated as a compound that crosses the mitochondrial membrane and associates directly with internal mitochondrial structures. This unusual targeting is the central reason it has attracted interest in cellular-energy and age-related-decline research.
Studied mechanisms of action
SS-31 is reported to bind cardiolipin, a phospholipid unique to the inner mitochondrial membrane that is essential for the organisation of the electron-transport chain. In research models, this interaction is studied for its potential to stabilise mitochondrial architecture, support efficient ATP production and reduce the generation of reactive oxygen species that accompany mitochondrial stress. Because cardiolipin integrity declines in many models of ageing and metabolic dysfunction, SS-31 is examined as a tool for probing whether membrane stabilisation can preserve mitochondrial output under stress.
The state of the research
SS-31 has been studied across a range of preclinical models touching cardiac, muscular, renal and neurological tissue, and has progressed into clinical investigation for certain mitochondrial conditions under its elamipretide designation. Within the research-compound community its use remains experimental, and results are model-dependent: outcomes vary with tissue type, dosing schedule and the nature of the mitochondrial stress being modelled. It is frequently studied alongside compounds such as MOTS-c and NAD+ in broader metabolic and longevity research.
Handling & storage for research
Supplied as a lyophilised powder. Store sealed vials cold and protected from light; reconstitute with bacteriostatic water for laboratory handling and keep the reconstituted solution refrigerated, using it within the appropriate window. Avoid repeated freeze-thaw cycles and vigorous agitation, which can degrade peptide integrity. Every Aura Labs batch ships with a third-party certificate of analysis confirming identity and purity above 99%.
Why researchers choose Aura Labs
Aura Labs supplies research peptides across Southeast Asia with third-party testing on every batch, a certificate of analysis available for each lot, and discreet, fast regional dispatch. Purity, accurate labelling and reproducible quality are the priorities researchers rely on for consistent results.
