Lyophilized MUST BE RECONSTITUTED

SS-31, also known as MTP-131, or Szeto–Schiller peptide, is a synthetic mitochondria-targeting tetrapeptide designed exclusively for laboratory and preclinical research applications. This peptide is widely studied in experimental settings focused on mitochondrial bioenergetics, oxidative stress mechanisms, and cellular energy dynamics.

SS-31 possesses a unique cationic and aromatic amino acid structure that enables efficient cellular penetration and selective localization to the inner mitochondrial membrane. The peptide demonstrates a strong affinity for cardiolipin, a key phospholipid responsible for maintaining mitochondrial membrane integrity and organizing the electron transport chain. These properties make SS-31 a valuable research tool for studying mitochondrial structure, stability, and function under stress conditions.

Due to its small molecular size and well-characterized structure, SS-31 is frequently used in in vitro and preclinical research models involving mitochondrial dysfunction, metabolic stress, and oxidative damage pathways. This product is supplied as a high-purity, lyophilized peptide powder and is intended strictly for research use only.
