Product Information
Total Active Ingredient: 600mg (20mg per capsule × 30 capsules)
SS-31 Capsules: Elamipretide for Mitochondria-Targeted Research
SS-31 (Elamipretide; D-Arg-Dmt-Lys-Phe-NH₂) is a cell-permeable, mitochondria-targeted tetrapeptide that selectively accumulates at the inner mitochondrial membrane (IMM) where it binds cardiolipin, a unique phospholipid essential for cristae architecture and electron transport chain function. Phase II/III clinical trials have been conducted for heart failure, Barth syndrome, and Friedreich's ataxia. These capsules (20mg per capsule, 30 capsules) support oral delivery research protocols.
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 restoration: restores ATP/ADP ratios in models of mitochondrial dysfunction and ischaemia
- Mitochondrial morphology: promotes fusion and reduces pathological fission in cardiomyocyte and neuron models
Research Areas
SS-31 capsules are studied in mitochondrial disease, cardiac failure models, ageing-associated mitochondrial decline, and neurodegenerative research. Commonly combined with MOTS-c and NAD+ in mitochondrial biology research panels.
Independent Lab Verification
Rainbow Peptide works with independent, accredited third-party laboratories, including Vanguard Laboratory (ISO 17025:2017-accredited, A2LA Certificate #6377.01.01), to verify compound identity and purity. A Certificate of Analysis is included with every order.
For Research Use Only. Rainbow Peptide supplies this compound exclusively for in vitro and laboratory research purposes. Not for human or veterinary use.
Frequently Asked Questions
- What is SS-31 Capsules (20mg)?
- SS-31 (Elamipretide) mitochondria-targeted tetrapeptide in oral capsule format, 20mg per capsule. Phase II/III clinical data for cardioprotection and mitochondrial bioenergetics. COA included.
- Is SS-31 Capsules (20mg) for sale at Rainbow Peptide?
- Yes. SS-31 Capsules (20mg) is available for purchase with Certificate of Analysis confirming >98% HPLC purity. Every order Overnight and 2–3 day delivery available. For Research Use Only.
- What purity is your SS-31 Capsules (20mg)?
- Rainbow Peptide's SS-31 Capsules (20mg) is >98% pure, HPLC verified through independent third-party laboratory testing, including work performed by Vanguard Laboratory (ISO 17025:2017-accredited, A2LA Certificate #6377.01.01). A COA is included with every order.
- What does the Certificate of Analysis actually verify?
- A COA reports identity (confirming the compound is what it's labeled as, via HPLC-UV/VIS matched against a reference standard) and assay/content (the measured purity percentage). Together, this verifies a batch matches its labeled specification, rather than relying on a purity claim alone.
- Is SS-31 Capsules (20mg) safe for human use?
- No. SS-31 Capsules (20mg) is strictly For Research Use Only (RUO). It is not intended for human consumption and is not intended to diagnose, treat, cure, or prevent any disease.
