SS-31 (elamipretide) is a cell-permeable tetrapeptide that selectively associates with cardiolipin on the inner mitochondrial membrane, helping to restore electron-transport efficiency and limit reactive oxygen production in stressed cells. Because mitochondrial dysfunction underlies many disease models, this peptide is widely requested for bioenergetics and oxidative-stress studies. Each vial contains a white lyophilized powder with purity verified by HPLC, and batch-specific data can be provided on request. The product maintains stability for extended periods when stored frozen or refrigerated in its original sealed container, and reconstituted solutions should follow your validated protocol. We supply customers across academic, biotech and industrial sectors, and our export department coordinates documentation, customs and courier selection for each destination country.
