Product Detail

1. Product Introduction

SS‑31 2S50 is a synthetic tetrapeptide composed of four amino‑acid residues.

CAS No.: 736992‑21‑5

Laboratory work focuses on its receptor binding features and intracellular biochemical signal responses within cell‑based test systems. All research data apply only to in‑vitro laboratory environments.

This product is lyophilized powder, for laboratory research use only. It shall not be administered to human beings, used in clinical trials or for any medical and cosmetic purposes.

2. Product Characteristic Features

SS‑31 2S50 is manufactured via standard solid‑phase synthesis and HPLC purification process.

The finished lyophilized powder maintains stable molecular conformation and good water‑soluble property.

Vacuum freeze‑drying process slows molecular degradation and keeps molecular structure stable during transportation and low‑temperature storage.

3. Main Research Application Directions

For in‑vitro laboratory experimental research only:

Fundamental study on interaction between polypeptide and receptor
Exploration of peptide‑mediated intracellular signal transduction within cell models
Research on molecular interaction of synthetic tetrapeptide
Stability comparison test of polypeptide under different solvent and culture conditions
Biochemical exploration for peptide‑related signal pathways

4. Specifications & Quality Standard

Appearance: White or off‑white lyophilized crystalline powder
Purity: ≥98% (HPLC high‑performance liquid chromatography detection)
Solubility: Soluble in sterile purified water and neutral PBS buffer solution
Molecular Formula: C₃₂H₄₉N₉O₅
Molecular Weight: 639.79 Da
Moisture content: ≤2.0%
Quality control: Complete COA report is provided for each batch, including HPLC purity test and impurity screening
Batch stability: Mature synthesis and purification technology ensures consistent quality among batches

5. Packaging & Storage Specifications

Conventional packaging: Vacuum lyophilized vial packaging; customized packaging is available for bulk purchase
Packaging advantage: Aseptic light‑proof sealed vial, moisture‑resistant to avoid molecular inactivation
Storage requirement: Store at -20℃ under sealed condition, keep away from light and humidity; avoid repeated freeze‑thaw cycles
Shelf life: 24 months under recommended low‑temperature sealed storage condition

6. Applicable Scenarios

Suitable for university laboratories, biochemical research institutes and cell‑biology research groups, for in‑vitro cell and molecular‑biology experimental study.

Important Notice: For laboratory research use only. Not for human consumption or clinical trials.

ECHEMI Editorial Reference

Elamipretide has been used in trials studying the treatment of Leber's Hereditary Optic Neuropathy.
Elamipretide, also known as MTP 131, is a mitochondria-targeted peptide antioxidant. Elamipretide decreases inflammation and protect against a variety of neurological illnesses. Elamipretide (SS-31) improves mitochondrial dysfunction, synaptic and memory impairment induced by lipopolysaccharide in mice. Elamipretide Promotes Mitophagosome Formation and Prevents Its Reduction Induced by Nutrient Excess in INS1 β-cells.
Elamipretide Synthetic is a single, non-glycosylated polypeptide chain containing 4 amino acids, having a molecular mass of 640 Dalton and a Molecular formula of C32H49N9O5 .

Research

Class:

Mitochondria-targeted tetrapeptide (Szeto-Schiller peptide)

Status:

FDA-approved (Forzinity) — Accelerated Approval 2025

Mechanism:

A cell-permeable, synthetic tetrapeptide (D-Arg-Dmt-Lys-Phe-NH₂) that selectively concentrates in the inner mitochondrial membrane and reversibly binds to cardiolipin, a phospholipid essential for electron transport chain (ETC) function. By stabilizing cardiolipin, SS-31 restores mitochondrial bioenergetics, reduces cytochrome c peroxidase activity, and prevents oxidative damage in cells with impaired mitochondrial function.

Activity note:

SS-31 does not act via traditional receptor agonism. It binds cardiolipin with high selectivity in the inner mitochondrial membrane. Functional EC₅₀ values are context-dependent (cell type, stress model). Key electrophysiology studies report mitochondrial membrane potential restoration at nanomolar concentrations.
