Description
SS-31 (Elamipretide) is a synthetic mitochondria-targeting tetrapeptide, developed by Hazel Szeto and Peter Schiller as part of the Szeto-Schiller (SS) peptide class. LiveWell supplies it as a lyophilized vial in 10mg and 50mg sizes, strictly for in-vitro laboratory research use only.
Mechanism studied
SS-31 is characterised in the literature as accumulating in the inner mitochondrial membrane, where it binds cardiolipin — a phospholipid concentrated almost exclusively in that membrane and critical to mitochondrial structure. This selective cardiolipin interaction is the property most often examined in comparative mitochondrial-biology research.
