SS-31 25mg Overview
SS-31 25mg from Peptide Science is the synthetic 4-amino-acid Szeto-Schiller tetrapeptide (also designated Elamipretide), supplied as a lyophilised vial for in-vitro mitochondrial-stress and preclinical bioenergetics research. The compound is one of the most-cited mitochondria-targeted peptide research tools in published cardiology and aging literature.
Compound Class and Mechanism
SS-31 has the sequence D-Arg-Dmt-Lys-Phe-NH2 (where Dmt is 2,6-dimethyltyrosine), with the alternating cationic-aromatic residue pattern that gives the SS-class of peptides their characteristic mitochondria-targeting profile. Preclinical research has characterised the compound for direct binding to cardiolipin on the inner mitochondrial membrane, with reported downstream effects on electron-transport-chain organisation and mitochondrial ATP-synthesis efficiency in cell-culture and animal-model studies.

Reconstitution and Handling
The lyophilised vial reconstitutes with bacteriostatic water at the working concentration set by the principal investigator. Aliquoting reconstituted stock for single-use frozen storage is the standard preclinical handling practice cited in peptide-research literature.
Quality and Shipping
Each batch passes HPLC at greater than 99 percent purity, with mass-spectrometry identity confirmation. A Certificate of Analysis accompanies every order. Material is filled in a US laboratory under ISO 9001:2015-aligned quality systems and dispatched in temperature-monitored insulated packaging via overnight or two-day courier.
