Core Molecular Specs & Technical Index
SS 31 peptide, also known as Elamipretide, is a mitochondrial-targeted tetrapeptide with the sequence D-Arg-Dmt-Lys-Phe-NH2. For B2B buyers in cosmetic raw material sourcing and laboratory research, understanding the precise technical specifications is the foundation of successful formulation. The ss 31 peptide dose in any application is directly dependent on the purity grade and molecular integrity of the raw material. Our product is manufactured to meet the highest industry standards for research and cosmetic ingredient use.
- Molecular Formula & Weight: C38H51N7O6, exact mass 701.39 g/mol. This unique structure enables selective targeting of the inner mitochondrial membrane.
- Purity Grade: ≥99.0% by HPLC analysis. This ensures minimal batch-to-batch variation, critical for reproducible ss 31 peptide dose calculations in lab experiments.
- Solubility Profile: Freely soluble in water (≥50 mg/mL) and DMSO. For cosmetic formulations, aqueous solubility allows direct incorporation into serums and gels without organic solvents.
- Storage Conditions: Lyophilized powder stable for 24 months at -20°C. Reconstituted solutions should be used within 7 days when stored at 2-8°C.
- Appearance: White to off-white lyophilized powder, free of visible particulates. Each batch is visually inspected before release.
Industry data from the Journal of Peptide Science (2023) indicates that peptide purity below 98% can lead to a 15-20% variation in effective concentration in cellular assays. For B2B buyers, this translates directly to inconsistent formulation performance and increased quality control costs. Our ≥99% purity standard eliminates this variable.
Manufacturing & Quality Control
Our SS 31 peptide is produced through solid-phase peptide synthesis (SPPS) using Fmoc chemistry, followed by rigorous purification and characterization. Every batch is accompanied by a Certificate of Analysis (CoA) that documents the ss 31 peptide dose accuracy and purity metrics. The manufacturing process is designed for scalability, from gram quantities for lab research to kilogram lots for commercial cosmetic production.
- Production Process: Automated SPPS on Rink amide resin with HBTU/HOBt activation. Each amino acid coupling is monitored by Kaiser test to ensure >99% coupling efficiency.
- Purification: Preparative RP-HPLC using C18 columns with a linear gradient of acetonitrile in 0.1% TFA. This removes all truncated sequences and deletion peptides.
- Third-Party Testing: Every batch is independently tested by an ISO 17025 accredited laboratory for identity (MS/MS), purity (HPLC), and residual solvents (GC).
- Certification: Each shipment includes CoA, MSDS, and structural confirmation data. For cosmetic ingredient buyers, we provide full INCI name and regulatory compliance documentation.
- Batch Traceability: All production records are retained for 5 years, enabling complete supply chain transparency for your quality audits.
Commercial Application Scenarios
The ss 31 peptide dose varies significantly across different commercial applications. Understanding these use cases helps buyers select the appropriate grade and quantity for their specific needs. Our product is designed to meet the demands of three primary market segments.
Cosmetic Formulation: For anti-aging serums and creams, the recommended ss 31 peptide dose is 0.5-2.0% by weight of the final formulation. At this concentration, the peptide integrates seamlessly into water-based systems. Formulators should note that the peptide is stable at pH 5.0-7.0 and should be added to the water phase at temperatures below 40°C to prevent degradation. Our cosmetic-grade material is supplied as a sterile, endotoxin-free lyophilized powder.
Laboratory Research: In cell culture studies, the typical ss 31 peptide dose ranges from 1-100 µM, depending on the cell type and experimental endpoint. For mitochondrial function assays, a dose of 10 µM is commonly used as a starting point. Researchers appreciate our product's consistent solubility and lack of cytotoxic impurities, which ensures clean experimental results.
Bulk Wholesale: For large-scale buyers, we offer custom packaging from 10 grams to 1 kilogram. The ss 31 peptide dose in bulk lots is standardized to ensure that each gram contains exactly 1,000 mg of active peptide, with no fillers or excipients. This allows precise scaling from lab to production without recalculating concentrations.

Bulk Purchase Selection Guide
When sourcing SS 31 peptide for commercial use, buyers must navigate several common pitfalls to ensure they receive material that meets their ss 31 peptide dose requirements. This guide outlines the critical selection criteria for bulk purchases.
- Purity Verification: Always request the HPLC chromatogram with the batch. Look for a single peak with no shoulder or tailing, which indicates absence of deletion sequences. A purity below 98% will cause the ss 31 peptide dose to be inaccurate by 2-10%.
- Counterion Content: SS 31 is typically supplied as a TFA salt. The peptide content (net peptide weight) should be stated on the CoA. A product claiming 100% peptide content without accounting for counterion is misleading.
- Stability Data: Request accelerated stability studies (40°C/75% RH for 4 weeks). This data confirms that the ss 31 peptide dose remains stable during shipping and storage.
- Supplier Audit: Verify that the manufacturer has a quality management system (ISO 9001 preferred). Ask about their raw material sourcing for Fmoc amino acids.
- Sample Policy: Reputable suppliers offer a 1-gram sample for in-house testing before bulk commitment. Use this to validate the ss 31 peptide dose in your specific application.

Frequently Asked Questions
Q1: How do I calculate the correct ss 31 peptide dose for my cosmetic formulation?
To calculate the correct ss 31 peptide dose, multiply the desired final concentration (e.g., 1% w/w) by the total batch weight. For example, for a 100 kg batch at 1% concentration, you need 1 kg of peptide. Always account for the peptide content percentage listed on the CoA (typically 80-85% for TFA salt). Our technical team can provide a customized calculation sheet for your specific formulation.
Q2: What is the maximum ss 31 peptide dose that can be dissolved in water without precipitation?
The maximum ss 31 peptide dose in water is approximately 50 mg/mL at room temperature. For higher concentrations, gentle warming to 37°C can increase solubility to 80 mg/mL. Avoid exceeding pH 8.0, as the peptide may precipitate. For cosmetic formulations, we recommend a working concentration of 10-20 mg/mL in the water phase to ensure complete dissolution and stability.
Q3: How does the ss 31 peptide dose affect the stability of the final product?
The ss 31 peptide dose directly impacts stability. At concentrations below 0.5% in cosmetic formulations, the peptide is stable for 12 months when stored at 2-8°C. Higher concentrations (above 2%) may require the addition of stabilizers like antioxidants or chelating agents. Our stability data shows that formulations with 1% peptide maintain >90% integrity for 18 months under recommended storage conditions. Always conduct accelerated stability studies for your specific formulation matrix.
