Elamipretide For Sale

Direct Sourcing Overview: High-Purity Elamipretide for Laboratory Use

Elamipretide (also known as SS-31 or MTP-131) for sale is available to qualified academic, clinical, and institutional laboratories as a high-purity research chemical. Designated strictly for in vitro assays and preclinical animal models, research-grade Elamipretide requires verified sequence fidelity, high-performance liquid chromatography (HPLC) purity exceeding 98%, and documented endotoxin limits prior to experimental integration.

When purchasing Elamipretide (SS-31), investigative teams must prioritize analytical transparency. PX1 Research provides batch-specific Certificate of Analysis (COA) documentation generated by independent ISO 17025 accredited laboratories. Every lot undergoes rigorous reverse-phase HPLC (RP-HPLC) to confirm chemical purity and electrospray ionization mass spectrometry (ESI-MS) to verify molecular weight, ensuring that experimental variables remain tightly controlled across long-term studies.

Molecular Structure and Cardiolipin Affinity

Elamipretide is a cell-permeable, synthetic tetrapeptide with the amino acid sequence D-Arg-Dmt-Lys-Phe-NH2 (where Dmt represents 2',6'-dimethyltyrosine). Structural analysis demonstrates that its unique alternating aromatic-basic amino acid motif grants it a strong lipophilic cation nature. This allows the molecule to cross the outer mitochondrial membrane independently of membrane potential.

Preclinical investigations demonstrate that Elamipretide selectively targets and binds cardiolipin, an essential phospholipid localized predominantly within the inner mitochondrial membrane (IMM). Cardiolipin plays a critical structural role in organizing respiratory chain complexes into functional supercomplexes (respirasomes). By electrostatic and hydrophobic interactions with cardiolipin's negatively charged headgroups and acyl chains, Elamipretide stabilizes membrane architecture and prevents cardiolipin peroxidation under conditions of cellular stress.

Preclinical Mechanisms: Mitochondrial Bioenergetics and ATP Synthesis

In vitro data indicate that by stabilizing cardiolipin at the inner mitochondrial membrane, Elamipretide optimizes electron flux through respiratory Complexes I, II, III, and IV. In isolated mitochondrial preparations, treatment with Elamipretide has been shown to reduce electron leak at Complex I and III, thereby maintaining the proton motive force necessary for efficient oxidative phosphorylation.

Preclinical rodent models of metabolic stress and ischemia highlight that cardiolipin stabilization by Elamipretide preserves ATP production while simultaneously suppressing the overproduction of reactive oxygen species (ROS). Furthermore, by preventing cardiolipin oxidation, Elamipretide inhibits the release of cytochrome c into the cytosol, a key event in the initiation of the intrinsic apoptotic cascade. These mechanisms position the compound as a fundamental tool in mitochondrial research peptides science.

Supplier Quality Metrics: Verifying Elamipretide Purity and COAs

Evaluating a supplier when sourcing high-purity analytical compounds requires assessing specific quality parameters. Because subtle impurities or remnant organic solvents can alter mitochondrial bioenergetic readouts, laboratory researchers must demand complete analytical verification.

At PX1 Research, every batch of Elamipretide is manufactured in cGMP-compliant US facilities and subjected to a multi-tiered analytical screening process:

• RP-HPLC Analysis: Confirms chromatographic purity, ensuring that related peptide impurities or truncated sequences do not exceed 2.0% total area.

• Mass Spectrometry (ESI-MS): Verifies exact monoisotopic mass to confirm peptide identity.

• Endotoxin Testing: Enforces strict bacterial endotoxin thresholds (typically <0.01 EU/mg) using chromogenic LAL assays to prevent non-specific inflammatory signaling in cell culture or animal assays.

• Residual Solvent & Heavy Metal Analysis: Ensures complete removal of trifluoroacetic acid (TFA) salts and synthesis reagents that could confound enzymatic or mitochondrial assays.

Comparative Analysis: Elamipretide vs. Other Mitochondrial Peptides

To understand the distinct role of Elamipretide within experimental designs, researchers frequently compare it against other mitochondrial-active agents within the PX1 Research library. Unlike broad-spectrum antioxidants that non-selectively scavenge ROS in the cytosol, Elamipretide acts directly at the IMM cardiolipin interface.

When evaluated alongside mitochondrial-derived peptides, key functional differences emerge. For instance, MOTS-c is a mitochondrial ORF-derived peptide that primarily regulates nuclear gene expression and metabolic homeostasis via AMPK pathways under stress. Similarly, Humanin functions predominantly as a cytoprotective factor that interacts with extracellular receptors and cytosolic bax proteins to prevent apoptosis. In contrast, Elamipretide (SS-31) acts biophysically at the lipid-protein interface of the inner mitochondrial membrane, directly modulating electron transport chain efficiency and supercomplex stability.

Laboratory Reconstitution and Solvent Compatibility Guidelines

Elamipretide is supplied as a lyophilized, sterile powder to maximize long-term shelf stability. For in vitro and in vivo laboratory protocols, standard reconstitution techniques must be followed under aseptic conditions within a certified laminar flow hood.

• Primary Solvents: Lyophilized Elamipretide exhibits high solubility in sterile lab-grade water, phosphate-buffered saline (PBS, pH 7.4), or 0.9% sterile saline. For assays requiring low-volume, high-concentration stock solutions, concentrations up to 10 mg/mL are readily achieved.

• Dissolution Protocol: Allow the vial to equilibrate to room temperature before reconstitution to prevent moisture condensation. Gently add the diluent along the inner glass wall of the vial. Swirl gently; do not vortex vigorously, as excessive shear forces can disrupt peptide secondary structures.

• Working Dilutions: Once reconstituted in aqueous buffer, working solutions should be diluted directly into culture media or assay buffers immediately prior to experimental procedures.

Storage, Handling, and Degradation Mitigation

Maintaining peptide integrity over the duration of an experimental timeline requires adherence to strict storage protocols detailed in our peptide storage and handling guides.

• Lyophilized Powder: Store at -20°C for short-to-medium term storage (up to 12 months) or at -80°C for long-term storage. Ensure the container seal remains intact to protect against atmospheric humidity.

• Reconstituted Solutions: Liquid aliquots should be divided into single-use volumes using polypropylene or low-protein-binding microcentrifuge tubes to prevent adsorption loss. Store liquid aliquots at -80°C. Avoid repeated freeze-thaw cycles, which accelerate peptide bond cleavage and reduce functional titer.

• Degradation Vectors: Avoid exposing reconstituted solutions to direct light or elevated temperatures above 37°C for extended periods, as the 2',6'-dimethyltyrosine residue can undergo oxidative degradation if exposed to prolonged UV light.

Current Preclinical Research Frontiers and Experimental Applications

Literature evaluating Elamipretide spans several disciplines focused on bioenergetics, cellular aging, and organ preservation models. Researchers utilize the compound to probe fundamental questions regarding mitochondrial dysfunction:

• Ischemia-Reperfusion Injury Models: In rodent models of renal and cardiac ischemia, Elamipretide administration prior to or during reperfusion has been studied for its capacity to suppress ROS surges, preserve cristae structure, and mitigate tissue necrosis.

• Neurodegenerative In Vitro Assays: Investigators employ Elamipretide in neuronal cell lines (such as SH-SY5Y or primary cortical neurons) to evaluate protection against amyloid-beta or alpha-synuclein-induced mitochondrial fragmentation.

• Skeletal Muscle Bioenergetics: Rodent studies examining age-related sarcopenia assess how targeted cardiolipin protection affects force production, mitochondrial coupling efficiency, and fatigue resistance in aged muscle fibers.
