SS-31 is a mitochondria-targeted tetrapeptide that selectively binds cardiolipin in the inner mitochondrial membrane. Research focuses on its effects on mitochondrial cristae structure, electron transport chain efficiency, ATP production, and reactive oxygen species (ROS) reduction in cell and animal models.
SS-31 contains alternating aromatic and cationic residues that create an amphipathic structure. This allows cell-permeable uptake and selective concentration at the inner mitochondrial membrane through electrostatic interactions with cardiolipin, without requiring a mitochondrial targeting sequence.
Yes — every SS-31 order includes a Certificate of Analysis confirming ≥99% purity via HPLC, peptide sequence identity, and batch traceability for complete research documentation.
SS-31 (Elamipretide) is a aromatic-cationic tetrapeptide that selectively binds cardiolipin on the inner mitochondrial membrane studied as part of the mitochondrial cardiolipin peptide category. It is investigated in pre-clinical and in-vitro research models for its activity on cardiolipin stabilization, electron transport chain integrity, and mitochondrial ROS pathways studied in vitro. The compound is supplied as a lyophilized powder of ≥99% HPLC-verified purity and is intended exclusively for laboratory research use under qualified scientific supervision.
AscendLabz SS-31 (Elamipretide) is sourced from cGMP-aligned synthesis facilities and validated for identity, purity, and counter-ion content prior to release. Each lot is independently tested by HPLC, and a Certificate of Analysis (COA) detailing peak area, retention time, and batch number is provided with every order. This level of documentation is intended to support reproducible research and clear chain-of-custody record-keeping in academic and independent laboratory environments.
For research workflows, SS-31 (Elamipretide) is most commonly characterized in cell-culture and isolated-tissue models where investigators examine cardiolipin binding and mitochondrial membrane stabilization alongside complementary compounds in the mitochondrial-targeted research peptides class. Reference standards and dose-response controls should be established by each laboratory prior to experimental use, and all material should be handled by trained personnel using appropriate personal protective equipment.
Storage: Lyophilized SS-31 is stable at -20°C protected from light. Reconstituted peptide should be refrigerated at 2-8°C and used within 14 days. Lyophilized peptides should be kept in original sealed packaging until use to prevent moisture uptake.
Reconstitution: Bring the lyophilized vial to room temperature before opening. Reconstitute with bacteriostatic water by injecting solvent down the inner wall of the vial; do not direct the stream onto the lyophilized cake. Gently swirl — do not vortex or shake — until fully dissolved. Allow 5-10 minutes for complete solvation.
Handling: Use sterile technique throughout. Wipe vial septa with isopropyl alcohol before each draw. Document reconstitution date, solvent volume, and resulting concentration on the vial label for traceability.
Every batch of SS-31 (Elamipretide) is analyzed by reverse-phase HPLC and confirmed to be ≥99% pure. Mass spectrometry confirms molecular identity, and counter-ion / residual-solvent panels are performed where applicable. The full Certificate of Analysis ships with each order and is also archived by lot number.
No. SS-31 (Elamipretide) is supplied strictly for in-vitro laboratory research and is not approved by the FDA, EMA, or any regulatory authority for human or veterinary therapeutic use. It must not be administered to humans or animals. By purchasing, you confirm you are a qualified researcher and the material will be used only in a controlled laboratory setting.
All orders ship from the USA via tracked courier within 24-48 hours of payment confirmation. Domestic delivery typically arrives within 2-5 business days in discreet, temperature-stable packaging. Tracking is provided by email at the time of dispatch.
