Core Molecular Specs & Technical Index

MOTs-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a mitochondrial-derived peptide that has gained significant traction in advanced cosmetic formulation and laboratory research. For B2B buyers—including cosmetic chemists, raw material distributors, and contract manufacturers—understanding the precise technical specifications of MOTs-c peptide is essential for ensuring batch consistency and formulation efficacy. This peptide is characterized by its unique amino acid sequence and its role in cellular energy metabolism, making it a high-value ingredient for anti-aging and skin vitality products.

Basic Properties & Purity Standards

The standard commercial form of MOTs-c peptide is a lyophilized powder with a molecular weight of approximately 2,174.5 Da. High-purity material, typically ≥98% as determined by HPLC, is the industry benchmark for cosmetic applications. Lower purity grades may contain truncated sequences or oxidation by-products that compromise formulation stability and biological activity.

• Purity: ≥98% (HPLC) is the minimum standard for cosmetic-grade MOTs-c; research-grade often requires ≥99%.
• Solubility: Readily soluble in water and phosphate-buffered saline (PBS) at concentrations up to 10 mg/mL; limited solubility in organic solvents.
• Storage Conditions: Lyophilized powder stable at -20°C for 24 months; reconstituted solutions must be used within 72 hours when stored at 2-8°C.
• Appearance: White to off-white lyophilized powder, free of visible aggregates or discoloration.
• Sequence Confirmation: Mass spectrometry (MS) and amino acid analysis must confirm the correct primary structure for every production lot.

Industry data from the 2023 Peptide Therapeutics Symposium indicates that cosmetic-grade peptides with ≥98% purity demonstrate 40% higher fibroblast stimulation in vitro compared to batches with 95% purity, underscoring the critical role of specification adherence in raw material sourcing.

Manufacturing & Quality Control

Reliable MOTs-c peptide manufacturing follows a rigorous, multi-step process designed to eliminate impurities and ensure batch-to-batch reproducibility. B2B buyers must verify that their suppliers adhere to current Good Manufacturing Practices (cGMP) and provide comprehensive documentation for each production lot.

Production Process & Purification

The synthesis of MOTs-c peptide typically employs solid-phase peptide synthesis (SPPS) using Fmoc chemistry. After cleavage from the resin, the crude peptide undergoes preparative HPLC purification to achieve the target purity level. This step is critical for removing deletion sequences, truncated fragments, and residual solvents.

• Solid-Phase Synthesis: Automated SPPS with Fmoc-protected amino acids ensures high coupling efficiency and minimal racemization.
• Preparative HPLC: Reverse-phase C18 columns with gradient elution achieve baseline separation of target peptide from impurities.
• Lyophilization: Controlled freeze-drying preserves peptide integrity and produces a stable, free-flowing powder.
• Third-Party Testing: Independent laboratories verify purity, endotoxin levels (<1 EU/mg), and bioburden counts.
• Certification: Certificate of Analysis (CoA) must include HPLC chromatogram, MS spectrum, and residual solvent analysis.

Commercial Application Scenarios

MOTs-c peptide benefits extend across multiple commercial channels, from high-end cosmetic formulations to bulk laboratory research. Understanding these application scenarios helps buyers select the appropriate grade and packaging format for their specific needs.

Cosmetic Formulation

In cosmetic products, MOTs-c peptide is incorporated into serums, creams, and masks at concentrations ranging from 0.1% to 1.0%. Its primary function is to support mitochondrial health in skin cells, which is directly linked to cellular energy production and dermal matrix maintenance. Formulators must consider the peptide's stability in aqueous environments and may require encapsulation technologies for sustained release.

Lab Research & Bulk Wholesale

Research laboratories utilize MOTs-c peptide for in vitro studies on cellular metabolism, aging pathways, and mitochondrial function. Bulk wholesale buyers—such as raw material distributors and contract manufacturers—typically order quantities from 1 gram to 100 grams, requiring consistent purity across all lots. Custom packaging options, including vacuum-sealed vials and nitrogen-flushed bags, are available to maintain stability during transit and storage.

Bulk Purchase Selection Guide

When sourcing MOTs-c peptide for commercial or research applications, B2B buyers must navigate several common pitfalls to ensure they receive material that meets their specifications. A systematic selection process minimizes risk and maximizes value.

Common Pitfalls & Selection Standards

One frequent issue is the misrepresentation of purity levels. Some suppliers quote "≥98%" but provide CoAs from in-house testing without third-party verification. Always request independent HPLC and MS data. Another concern is improper storage during shipping, which can degrade the peptide before it reaches your facility. Verify that your supplier uses cold-chain logistics for international orders.

• Request Full Documentation: CoA, MSDS, and stability data should be provided before purchase.
• Verify Manufacturing Date: Fresher batches (less than 6 months old) have higher residual activity.
• Check Packaging Integrity: Vacuum-sealed, desiccated vials are essential for long-term stability.
• Confirm Regulatory Compliance: Ensure the supplier follows cGMP and provides certificates for cosmetic-grade material.
• Evaluate Technical Support: Suppliers offering formulation guidance and troubleshooting add significant value.

Core Product Advantages

High-purity MOTs-c peptide offers distinct advantages over lower-grade alternatives, making it the preferred choice for serious cosmetic formulators and research laboratories. These benefits directly impact product performance, safety, and cost efficiency.

Purity & Stability

The ≥98% purity threshold ensures that the peptide's biological activity is maximized while minimizing the risk of immunogenic reactions or formulation instability. High-purity MOTs-c peptide also exhibits superior thermal and hydrolytic stability, allowing for longer shelf life and more flexible formulation conditions.

Cost Performance & Technical Support

While high-purity MOTs-c peptide commands a premium price, its consistent performance reduces batch failures and rework costs. Additionally, reputable suppliers provide technical support for formulation optimization, including solubility testing, pH stability profiles, and compatibility studies with common cosmetic excipients. This support translates into faster product development cycles and lower overall costs for B2B buyers.

Frequently Asked Questions

Q1: What is the recommended storage condition for MOTs-c peptide after reconstitution?
After reconstitution in sterile water or PBS, MOTs-c peptide should be stored at 2-8°C and used within 72 hours. For longer storage, aliquot the solution and freeze at -20°C, avoiding repeated freeze-thaw cycles which can degrade the peptide.

Q2: How does MOTs-c peptide purity affect cosmetic formulation stability?
Higher purity (≥98%) reduces the presence of truncated sequences and oxidation by-products that can catalyze degradation reactions in the formulation. This results in a longer shelf life and more consistent product performance over time.

Q3: Can MOTs-c peptide be used in combination with other active ingredients in cosmetic products?
Yes, MOTs-c peptide is compatible with many common cosmetic actives, including hyaluronic acid, vitamin C, and retinoids. However, compatibility testing is recommended, particularly with strong acids or reducing agents that may affect peptide stability. Formulators should conduct accelerated stability studies to confirm compatibility.
