SS-31 (also known as Elamipretide) is a mitochondria-targeting tetrapeptide widely studied for its role in cellular energy dynamics and mitochondrial integrity. At Peptide Hubs, our SS-31 50mg Peptide is supplied with 99% purity, making it a premium option for laboratories and researchers focused on advanced peptide and mitochondrial research applications. SS-31 is uniquely designed to selectively associate with cardiolipin in the inner mitochondrial membrane. This interaction has made it a subject of extensive scientific interest in studies exploring mitochondrial structure, oxidative processes, and cellular bioenergetics. Its small molecular size supports efficient cellular uptake, which is why it is frequently referenced in experimental research models examining mitochondrial performance.
