Product Information

SS-31 | Elamipretide — Mitochondria-Targeted Peptide — Research Grade

SS-31 (Elamipretide; D-Arg-Dmt-Lys-Phe-NH2) is a cell-permeable, mitochondria-targeted tetrapeptide that selectively accumulates in the inner mitochondrial membrane (IMM) where it binds cardiolipin, a unique phospholipid essential for cristae architecture and electron transport chain function.

Mechanism of Action

  • Cardiolipin binding — stabilises cardiolipin in the IMM, maintaining cytochrome c attachment and preventing its pro-apoptotic release
  • ETC optimisation — improves electron flow through Complexes I, III, and IV, reducing electron leak and ROS production
  • ATP synthesis — restores ATP/ADP ratios in models of mitochondrial dysfunction and ischaemia
  • Mitochondrial morphology — promotes fusion and reduces fission in cardiomyocyte and neuron models

Research Areas

SS-31 is studied in heart failure (Phase II/III clinical trials as Elamipretide), ischaemia-reperfusion injury, Alzheimer disease, Parkinson disease, renal disease, and age-related mitochondrial decline.

For Research Use Only. Rainbow Peptide supplies SS-31 exclusively for in vitro and laboratory research purposes. Not for human or veterinary use.

GHK-Cu lot was outstanding

We use GHK-Cu in dermal fibroblast research. This lot performed exactly as expected — >98% purity HPLC. The COA cited the reference standard lot number. That detail is rare at this price point.

Best Epithalon sourcing this quarter

Sourced Epithalon from three vendors this quarter. Rainbow Peptide had the most detailed COA and lowest endotoxin levels measured. Will be primary source for our current project.

Good peptide, delivered fast

GHK-Cu arrived in 2 business days. Cold pack still active on delivery. Peptide dissolved cleanly in bacteriostatic water. COA was comprehensive. Happy with this purchase.
