SS-31 (Elamipretide) (CAS 736992-21-5) is mitochondria-associated synthetic tetrapeptide. It is a compact aromatic-cationic peptide designed for studies of mitochondrial membrane organization and cellular bioenergetics. The material is supplied for laboratory research in a lyophilized format and can support biochemical, cellular, molecular, and comparative model development where a defined peptide reagent is required.

As a research tool, SS-31 (Elamipretide) offers a practical bridge between sequence-defined chemistry and complex biological models. It can be incorporated into pathway-focused studies, concentration-response experiments, time-course designs, biomarker panels, and comparative work with analogs or controls. Its role is to help researchers test mechanisms under controlled conditions, not to predetermine the outcome.

Mechanism and Scientific Rationale

Cardiolipin-associated membrane research. SS-31 is widely used to examine peptide interactions with cardiolipin-rich inner mitochondrial membranes. Experimental work investigates how this association may influence membrane curvature, protein organization, electron-transfer efficiency, and the local environment surrounding respiratory complexes without assuming a single universal outcome across models.

Mitochondrial redox balance. Cell and tissue models use SS-31 to explore the relationship between mitochondrial electron handling, reactive species formation, antioxidant capacity, and macromolecular integrity. The peptide is useful for separating membrane-centered events from downstream changes in cellular stress signaling.

Bioenergetic performance. Researchers evaluate oxygen consumption, membrane potential, ATP-linked respiration, reserve capacity, and metabolic flexibility after controlled exposure to SS-31. These endpoints support mechanistic comparisons across normal, stressed, aged, or genetically altered systems.

Organelle quality-control pathways. SS-31 is also studied alongside mitochondrial dynamics, turnover, autophagic processing, and organelle-to-nucleus communication. Such designs help determine whether observed cellular effects arise from immediate membrane interactions or from longer adaptive responses.
