ŚŚ-31 Research Overview

SS-31 (listed here as ŚŚ-31) is a cell-permeable, mitochondria-targeted tetrapeptide from the Szeto-Schiller (SS) family of peptides. ŚŚ-31 is supplied for qualified in-vitro laboratory research and analytical use only.

Compound profile

  • Compound class: Mitochondria-targeted synthetic tetrapeptide
  • Sequence: D-Arg-Dmt-Lys-Phe-NH₂ (Dmt = 2′,6′-dimethyltyrosine)
  • Molecular weight: ≈ 639.8 g/mol
  • CAS number: 736992-21-5
  • Form: Lyophilized powder in a sealed vial
  • Testing: Third-party HPLC purity and identity, batch-matched COA

Research context

SS-31 concentrates in the inner mitochondrial membrane, where it associates with the phospholipid cardiolipin. Research examines its effects on cristae structure, electron-transport-chain efficiency, ATP production and reactive-oxygen-species generation in cardiac, skeletal-muscle, renal and aging models of mitochondrial dysfunction.

Storage and handling

Store unopened lyophilized vials sealed and protected from light — at −20 °C for long-term storage, or 2–8 °C for short-term use. Once reconstituted, keep refrigerated at 2–8 °C, minimize freeze–thaw cycles and rely on your laboratory’s own validated stability data.

Quality and documentation

Every lot is third-party tested, and the Certificate of Analysis is matched to the exact batch you receive — look it up any time on the COA page. Browse more Mitochondrial & Cellular Energy Research, or see related compounds: MOTS-C, NAD+ (Nicotinamide Adenine Dinucleotide).
