SS-31 is a synthetic mitochondria-targeting tetrapeptide widely studied in laboratory settings for its interaction with mitochondrial membranes and cellular energy production pathways. Its unique affinity for cardiolipin has made it a key compound in mitochondrial research, particularly where oxidative stress, ATP production and cellular bioenergetics are being investigated.

In controlled research environments, SS-31 is commonly used in studies exploring mitochondrial function, membrane stability, oxidative stress, cellular metabolism, energy signalling pathways and mitochondrial integrity across a range of experimental models. Its well-characterised synthetic structure and high purity make it suitable for advanced in-vitro applications requiring consistency, analytical reliability and reproducible research outcomes.
