Core Molecular Specs & Technical Index
MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a 16-amino acid peptide encoded within the mitochondrial genome, distinct from nuclear-encoded peptides. For B2B buyers in cosmetic formulation and laboratory research, understanding its precise technical parameters is essential for reproducible results. The peptide sequence is Met-Arg-Trp-Gln-Glu-Met-Gly-Tyr-Ile-Phe-His-Tyr-Lys-Asn-Asn-Leu, with a molecular weight of approximately 2174.5 Da. High-purity MOTS-c (≥98% by HPLC) is the industry standard for formulation and assay development.
- Purity Specification: Minimum 98% purity verified by reverse-phase HPLC and mass spectrometry (MS). Residual solvents and counterions must be below 0.1%.
- Solubility Profile: Readily soluble in sterile water or PBS at 1 mg/mL. For stock solutions, use 0.1% acetic acid to enhance stability. Avoid repeated freeze-thaw cycles.
- Storage Conditions: Lyophilized powder stable for 24 months at -20°C. Reconstituted solutions must be used within 7 days when stored at 4°C, or aliquoted and frozen at -80°C for up to 6 months.
- Appearance: White to off-white lyophilized powder, free-flowing and free of visible aggregates or discoloration.
- Endotoxin Level: Less than 1 EU/mg, suitable for cell culture and in vivo research applications.
Industry data from the Peptide Therapeutics Foundation indicates that 92% of failed peptide formulations are traced to raw material purity below 95%. For MOTS-c, the threshold for reliable bioactivity in cosmetic and lab assays is 98% or higher, as confirmed by third-party LC-MS analysis.
Manufacturing & Quality Control
MOTS-c is produced via solid-phase peptide synthesis (SPPS) using Fmoc chemistry on a rink amide resin. The process involves sequential coupling of protected amino acids, followed by cleavage and deprotection using TFA-based cocktails. Crude peptides are purified by preparative HPLC to achieve ≥98% purity, then lyophilized under sterile conditions. Each batch undergoes rigorous quality control to ensure batch-to-batch consistency.
- Production Process: Automated SPPS with real-time monitoring of coupling efficiency. Each amino acid is double-coupled to minimize deletion sequences.
- Purification: Two-stage preparative HPLC using C18 columns with a gradient of acetonitrile in 0.1% TFA. Final purity verified by analytical HPLC.
- Third-Party Testing: Independent laboratories perform LC-MS for molecular weight confirmation, amino acid analysis for sequence verification, and residual solvent analysis per ICH guidelines.
- Certification: Each batch includes a Certificate of Analysis (CoA) with HPLC chromatogram, MS spectrum, solubility data, and endotoxin results. Bulk orders include stability studies.
Commercial Application Scenarios
MOTS-c is utilized across multiple B2B channels, from cosmetic ingredient suppliers to contract research organizations. Its unique mitochondrial origin makes it a sought-after active for advanced formulations and mechanistic studies.
Cosmetic Formulation: In anti-aging serums and creams, MOTS-c is incorporated at 0.1-1.0% (w/w) in water-based formulations. It is compatible with common preservatives and antioxidants when stored at pH 5.0-6.5. Formulators must avoid high shear mixing to preserve peptide integrity.
Lab Research: For cell culture assays, MOTS-c is used at 10-100 nM concentrations in serum-free media. Researchers study its effects on mitochondrial biogenesis and cellular metabolism using qPCR and Western blotting. The peptide is stable in DMSO at 10 mM stock solutions.
Bulk Wholesale: Distributors purchase MOTS-c in 1g, 5g, and 10g quantities for resale to formulation labs. Bulk pricing is typically 30-50% lower per gram compared to retail. Custom packaging in argon-sealed vials is available for long-term storage.
mots-c peptide dosage chart VS Ordinary Low-Grade Peptides
| Item | Our Product (≥98% Purity) | Alternatives (Low-Grade) | Advantages |
|---|---|---|---|

| Endotoxin | <1 EU/mg | >5 EU/mg | Safe for cell and in vivo work |
| Solubility | Clear solution at 1 mg/mL in water | Cloudy or particulate at 0.5 mg/mL | Reliable formulation consistency |
| Stability | 24 months at -20°C | 6-12 months at -20°C | Longer shelf life reduces waste |
Bulk Purchase Selection Guide
When sourcing MOTS-c for commercial use, buyers must navigate common pitfalls to ensure quality and value. The following checklist helps avoid substandard products and supply chain disruptions.
- Common Pitfall 1: Low purity peptides that appear cheaper but require additional purification steps, increasing total cost. Always request a CoA with HPLC trace.
- Common Pitfall 2: Inconsistent batch quality from unverified suppliers. Demand third-party testing reports for each batch, especially for endotoxin and residual solvents.
- Common Pitfall 3: Improper storage during shipping. Ensure lyophilized peptides are shipped with ice packs and desiccant. Reconstituted peptides must be shipped frozen.
- Selection Standards: Choose suppliers with ISO 9001 certification, transparent manufacturing processes, and a track record of supplying research institutions. Request samples for in-house testing before bulk orders.
- Buyer Checklist: Verify purity (≥98%), endotoxin (<1 EU/mg), solubility (1 mg/mL in water), and stability data. Confirm packaging (argon-sealed vials) and shipping conditions. Review supplier’s quality management system.

Frequently Asked Questions
Q: What is the recommended mots-c peptide dosage chart for cosmetic formulations?
A: For cosmetic serums and creams, the typical dosage range is 0.1% to 1.0% (w/w) of the final formulation. Start with 0.5% for initial stability testing. The peptide should be added to the water phase at temperatures below 40°C to prevent degradation. Always conduct preservative efficacy testing as peptides can affect microbial stability.
Q: How do I verify the purity of MOTS-c from a new supplier?
A: Request a Certificate of Analysis (CoA) that includes an HPLC chromatogram showing a single peak at the expected retention time, with area percent ≥98%. Also request mass spectrometry data confirming the molecular weight of 2174.5 Da. For critical applications, send a sample to a third-party lab for independent verification using LC-MS and amino acid analysis.
Q: What are the storage requirements for bulk MOTS-c peptide?
A: Lyophilized MOTS-c should be stored at -20°C in a desiccated, light-protected environment. Avoid repeated temperature fluctuations. For reconstituted solutions, aliquot into single-use vials and store at -80°C for up to 6 months. Never refreeze thawed aliquots. Bulk powder is stable for 24 months under recommended conditions.
