SS-31 is a mitochondria-targeted antioxidant peptide supplied by Apex Laboratory as a high-purity research peptide intended strictly for in-vitro laboratory research and development applications.

Compound Overview

SS-31 (Elamipretide) is a cell-permeable tetrapeptide that selectively concentrates in the inner mitochondrial membrane by binding cardiolipin. This interaction stabilizes cytochrome c and optimizes electron transport chain function, reducing mitochondrial ROS production. It is the most studied mitochondria-targeted peptide.

Research Background & Published Literature

Developed by Dr. Hazel Szeto. Published in Clinical Pharmacology & Therapeutics and JACC. Clinical trials have investigated it in heart failure (TANGO), Barth syndrome, and age-related mitochondrial dysfunction. A key research tool for studying mitochondrial medicine.

Researchers interested in the published literature surrounding this compound can explore the following peer-reviewed resources for additional context on its mechanism of action, signaling pathways, and experimental applications in controlled laboratory settings:

Storage, Handling & Stability Guidelines

Store lyophilized material at -20°C for long-term stability. After reconstitution with sterile diluent, refrigerate at 2–8°C and minimize freeze-thaw cycles by aliquoting working volumes according to your standard operating procedures.

  • Minimize time at ambient temperature during handling to preserve compound integrity.
  • Avoid moisture exposure by resealing vials promptly after each withdrawal.
  • Use appropriate personal protective equipment and follow your institution’s chemical safety protocols at all times.
  • Label all aliquots with the compound name, concentration, date of reconstitution, and operator initials for complete traceability.

Quality Assurance & Analytical Verification

Apex Laboratory applies a dual-verification quality protocol to every batch before it enters inventory. Each lot undergoes High-Performance Liquid Chromatography (HPLC) to confirm chromatographic purity and Mass Spectrometry (MS) to verify molecular identity and molecular weight. This two-step analytical process ensures that the material you receive meets our ≥99% purity standard with confirmed molecular integrity. Certificates of Analysis documenting these results are available in the batch verification panel on this page and in the COA library for your internal quality records.
