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. All lots pass strict quality verification and lot-specific certificates can be provided on request. Keep unopened material sealed at 2-8 degree C away from light and moisture; store at -20 degree C for longer periods and avoid repeated freezing. We accept small trial and large bulk orders and provide OEM, private-label and neutral discreet-packaging services with global delivery. Laboratory research use only.
