Core Molecular Specs & Technical Index
MOTS-c (mitochondrial open reading frame of the 12S rRNA-c) is a 16-amino acid peptide that has gained significant traction in the cosmetic and biotech raw material sectors. For B2B buyers—including formulation chemists, contract manufacturers, and peptide distributors—understanding the mots c peptide benefits begins with its precise molecular profile. This peptide is characterized by a molecular weight of approximately 2,174.5 Da and a sequence that targets mitochondrial function at the cellular level. In cosmetic applications, the primary value lies in its ability to support cellular energy metabolism and dermal matrix integrity, making it a high-potential active ingredient for anti-aging and skin rejuvenation formulations.
- Purity Standard: Minimum 98% purity verified by HPLC, with premium grades offering 99%+ for injectable or high-end topical serums.
- Solubility Profile: Readily soluble in water and PBS buffer at 1 mg/mL, with optimal stability in lyophilized powder form.
- Storage Conditions: Lyophilized powder stable at -20°C for 24 months; reconstituted solution must be used within 72 hours at 2-8°C.
- Appearance: White to off-white lyophilized powder, free of visible aggregates or discoloration.
- Endotoxin Level: Less than 1 EU/mg for cosmetic-grade material, ensuring minimal irritation risk in topical applications.
Industry data from the 2023 Peptide Therapeutics Market Report indicates that mitochondrial-targeting peptides like MOTS-c have seen a 34% year-over-year increase in cosmetic raw material procurement, driven by demand for energy-boosting skincare actives.
Manufacturing & Quality Control
The production of high-purity MOTS-c requires a multi-step process that ensures batch-to-batch consistency and biological activity. Solid-phase peptide synthesis (SPPS) is the industry standard, followed by reverse-phase high-performance liquid chromatography (RP-HPLC) purification. For B2B buyers, the critical quality control parameters include peptide content, counterion content, and residual solvent analysis. Third-party testing by ISO 17025 accredited laboratories is recommended to verify the certificate of analysis (COA) provided by suppliers.
- Production Process: SPPS using Fmoc chemistry, with real-time monitoring of coupling efficiency.
- Purification: Preparative HPLC achieving >98% purity, with analytical HPLC confirmation.
- Third-Party Testing: Mass spectrometry (MS) for molecular weight confirmation, amino acid analysis for sequence verification.
- Certification List: COA, MSDS, HPLC chromatogram, and stability data for each batch.
- Quality Assurance: Each batch is tested for pH, osmolality, and sterility if intended for lab research applications.
Commercial Application Scenarios
The mots c peptide benefits are most effectively leveraged in three primary commercial contexts. In cosmetic formulation, MOTS-c is incorporated into serums, creams, and masks at concentrations ranging from 0.1% to 1% to support skin energy metabolism and reduce visible signs of aging. For lab research, it is used as a tool compound in mitochondrial function assays and dermal fibroblast studies. Bulk wholesale buyers typically source MOTS-c in 1g, 5g, or 10g quantities for pilot batches or full-scale production runs.
- Cosmetic Formulation: Added to water-phase formulations at pH 5.5-6.5, with antioxidants to prevent oxidation.
- Lab Research: Reconstituted in sterile water for cell culture studies at 10-100 µM concentrations.
- Bulk Wholesale: Supplied in vacuum-sealed vials with desiccant, with custom packaging options for OEM clients.

Bulk Purchase Selection Guide
When sourcing MOTS-c for commercial use, B2B buyers must navigate common pitfalls to ensure they receive a product that delivers the expected mots c peptide benefits. The most frequent issues include mislabeled purity, inadequate documentation, and improper storage during transit. A systematic selection process based on verified specifications and supplier transparency is essential for maintaining product integrity.
- Common Pitfalls: Accepting COAs without HPLC chromatograms, ignoring endotoxin levels for topical use, and failing to verify storage conditions during shipping.
- Selection Standards: Require batch-specific COA with HPLC trace, MS confirmation, and stability data at recommended storage conditions.
- Buyer Checklist: Verify supplier ISO certification, request third-party test reports, confirm packaging integrity, and establish a quality agreement for bulk orders.

Frequently Asked Questions
Q1: What is the recommended concentration of MOTS-c in cosmetic formulations to achieve optimal mots c peptide benefits?
For topical serums and creams, the effective concentration range is typically 0.1% to 0.5% by weight. Higher concentrations up to 1% may be used in leave-on products, but stability testing is recommended to ensure no precipitation or degradation occurs over the product shelf life.
Q2: How should MOTS-c be stored after reconstitution to maintain its activity for lab research?
Reconstituted MOTS-c should be stored at 2-8°C and used within 72 hours. For longer storage, aliquot the solution and freeze at -20°C for up to 30 days. Avoid repeated freeze-thaw cycles, as this can reduce peptide activity by up to 20% per cycle.
Q3: What documentation should a B2B buyer request to verify the quality of bulk MOTS-c?
Request a batch-specific certificate of analysis (COA) that includes HPLC purity percentage, mass spectrometry confirmation, amino acid analysis, endotoxin levels, and residual solvent content. Additionally, request the material safety data sheet (MSDS) and stability data under recommended storage conditions.
