SS-31, also known as Elamipretide, is a synthetic tetrapeptide that selectively binds cardiolipin in the inner mitochondrial membrane, studied in mitochondrial and cardiovascular research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. SS-31 is investigated in research on mitochondrial function, oxidative stress, bioenergetics and cardiac protection, and is commonly applied in cell-based and preclinical studies. The lyophilized presentation provides excellent stability and reproducible reconstitution for consistent experimental dosing. Strict quality control is maintained on every batch, and COA is available for specific batches on request. Keep the unopened product sealed at 2-8 degree C away from light; -20 degree C is recommended for long-term storage avoiding repeated thawing. Small and bulk orders are both welcome, and OEM and discreet neutral packing are offered. For laboratory research use only, not for human or veterinary application.
