SS-31 (Elamipretide) — Mitochondria-Targeted Peptide

(134 reviews)
99.3% Purity
$149.99per 5 mg · lyophilized

SS-31 (Elamipretide) is a synthetic D-Arg-Dmt-Lys-Phe-NH₂ tetrapeptide that selectively targets the inner mitochondrial membrane. Its positive charge and aromatic residues facilitate accumulation at cardiolipin-rich mitochondrial membranes, where it scavenges reactive oxygen species, stabilizes cytochrome c, and preserves cristae architecture. Research applications include cardiac ischemia-reperfusion models, aging-related mitochondrial dysfunction studies, and neurodegenerative disease models. For research use only — not for human consumption.

Independent Verification

Third-Party Tested. Every Lot.

Every batch of SS-31 undergoes independent HPLC and mass spectrometry analysis through an accredited third-party laboratory before it is released for sale. No exceptions. No internal-only certificates.

RP-HPLC Analysis

Every lot measured by reverse-phase HPLC. SS-31 consistently achieves 99.3%+ purity across batches.

ESI Mass Spec

Electrospray ionization mass spectrometry confirms exact molecular weight and rules out structural isomers or impurities.

Lot-Specific CoA

Your Certificate of Analysis references your exact lot number with actual chromatogram data — not a generic template.
