Product Overview

SS-31 is a cell-permeable, mitochondria-targeted synthetic peptide that has become an important research tool in the study of mitochondrial membrane dynamics and cellular energy metabolism. It selectively accumulates at the inner mitochondrial membrane, where it interacts with cardiolipin — a phospholipid critical to mitochondrial structure and function. This targeted interaction makes SS-31 a highly sought-after compound for researchers exploring oxidative stress reduction, ATP production efficiency, and age-related cellular decline. Available through Direct Anti Peptide, this vial-format product supports reproducible, high-precision experimental work.

Peptide Structure & Amino Acid Sequence

SS-31, also known by its research designation Elamipretide or MTP-131, is a tetrapeptide with the amino acid sequence D-Arg-2′6′-Dmt-Lys-Phe-NH₂. Its alternating aromatic and cationic residues confer a strong affinity for the anionic phospholipid cardiolipin. This structural configuration enables SS-31 to penetrate the mitochondrial inner membrane without dependence on membrane potential, making it a uniquely versatile tool for mitochondrial research under varying experimental conditions.

Purity & Analytical Verification (HPLC & MS)

Every SS-31 Peptide Vial supplied by Direct Anti Peptide undergoes rigorous analytical testing prior to release. High-performance liquid chromatography (HPLC) is employed to confirm peptide purity at ≥98%, ensuring minimal presence of truncated sequences, deletion peptides, or synthesis by-products. Mass spectrometry (MS) is used to verify the exact molecular weight and confirm structural identity. These dual-method verification protocols provide researchers with the analytical confidence required for reproducible, publication-quality experimental results.

Quality Control & Lyophilization Integrity

Lyophilization is the preferred preservation method for sensitive research peptides such as SS-31. The freeze-drying process removes moisture under vacuum conditions, significantly extending shelf life while preserving the peptide’s structural integrity, biological activity, and chemical stability. Each vial is sealed under inert conditions to prevent oxidation and contamination during storage and transit. Direct Anti Peptide’s quality control workflow ensures that every unit leaving our facility meets strict batch-to-batch consistency standards, giving researchers a reliable supply for ongoing studies.

Safety, Handling & Laboratory Precautions

SS-31 Peptide Vials are intended for use by trained laboratory professionals only. Standard laboratory safety protocols must be observed at all times. Researchers should wear appropriate personal protective equipment (PPE), including gloves, eye protection, and lab coats, when handling this compound. Avoid inhalation of lyophilized powder. This product is not approved for any use outside of controlled research settings and must be handled in compliance with all applicable institutional and regulatory guidelines governing research chemicals.

Reconstitution, Packaging & Storage

The SS-31 Peptide Vial is supplied in a sterile, sealed glass vial in lyophilized form. Reconstitution should be performed using appropriate laboratory-grade solvents in accordance with your institution’s standard operating procedures for research peptides. Once reconstituted, the solution should be aliquoted and stored as required by your experimental protocol. Lyophilized product should be stored at -20°C or below, protected from light and moisture. Under recommended storage conditions, stability is maintained for extended periods. Avoid repeated freeze-thaw cycles of reconstituted material.

Intended Research Use & Market Positioning

SS-31 is actively investigated in research contexts related to mitochondrial dysfunction, neurodegeneration, metabolic disorders, ischemia-reperfusion injury, and cellular aging. Its ability to reduce lipid peroxidation, support cardiolipin integrity, and enhance ATP synthesis efficiency makes it a valuable compound for studies in bioenergetics and longevity science. Direct Anti Peptide positions this product as a premium-grade, analytically verified research reagent designed to meet the demands of modern peptide science laboratories.
