Product Overview

SS-31, also known by its research designation Elamipretide, is a small synthetic tetrapeptide that has attracted significant scientific interest for its ability to selectively target the inner mitochondrial membrane. The pre-mixed pen format offered by Direct Anti Peptide is designed to bring convenience and consistency to laboratory settings, eliminating the need for manual reconstitution steps and reducing variability between research sessions. Available as individual pre-mixed cartridges or as part of a complete pen kit, researchers can select the configuration that best suits their experimental requirements.

Peptide Structure & Amino Acid Sequence

SS-31 is a tetrapeptide with the amino acid sequence D-Arg-Dmt-Lys-Phe-NH2, where Dmt denotes 2′,6′-dimethyltyrosine. This alternating cationic and aromatic residue architecture is central to the peptide’s documented affinity for cardiolipin, a phospholipid uniquely concentrated in the inner mitochondrial membrane. The aromatic residues facilitate electron scavenging properties, while the cationic residues support electrostatic interactions with anionic membrane components, enabling selective mitochondrial localization independent of mitochondrial membrane potential.

Purity & Analytical Verification (HPLC & MS)

Every batch of SS-31 Pre-Mixed Pen 25mg supplied by Direct Anti Peptide undergoes rigorous analytical testing prior to release. Purity is confirmed at ≥98% via high-performance liquid chromatography (HPLC), and molecular identity is verified through mass spectrometry (MS). Certificates of Analysis (CoA) are available upon request, providing researchers with full traceability and confidence in the integrity of each cartridge supplied.

Quality Control & Lyophilization Integrity

The SS-31 peptide used in this pre-mixed formulation is produced under strict quality control protocols. The lyophilization process preserves structural integrity and biological activity during transit and storage. Each cartridge is sealed under inert conditions to prevent oxidative degradation. Batch-to-batch consistency is maintained through standardized manufacturing procedures, ensuring that researchers receive a product that meets the same high specifications with every order placed through Direct Anti Peptide.

Safety, Handling & Laboratory Precautions

This product is intended exclusively for use by trained research professionals in properly equipped laboratory environments. Standard laboratory safety precautions must be observed at all times when handling this peptide. Appropriate personal protective equipment (PPE), including gloves, eye protection, and lab coat, should be worn. This compound must not be used in any context involving human subjects, animals, or any clinical or diagnostic procedure. Researchers are responsible for complying with all applicable local, national, and institutional regulations governing the handling and use of research peptides.

Reconstitution, Packaging & Storage

The SS-31 Pre-Mixed Pen 25mg is supplied in a pre-mixed cartridge format, removing the need for manual reconstitution in the laboratory. The complete pen kit includes an injection pen device, single-use needle tips, a protective carry case, and the pre-mixed cartridge — providing a streamlined setup for research applications. Individual cartridges are also available for researchers who already possess compatible pen hardware. Upon receipt, store at −20°C in a dry, dark environment. Avoid repeated freeze-thaw cycles to maintain formulation stability.

Intended Research Use & Market Positioning

SS-31 is an active subject of peer-reviewed research across multiple disciplines, including mitochondrial biology, cardiovascular science, nephrology, neurodegenerative disease models, and skeletal muscle physiology. Research has explored its role in stabilizing cardiolipin, reducing oxidative stress, restoring ATP production, and supporting mitochondrial bioenergetics. Areas of documented scientific interest include models of kidney disease, Barth syndrome, heart failure, and age-related mitochondrial decline. Direct Anti Peptide positions this product exclusively for in vitro and preclinical research use by qualified investigators.
