Core Molecular Specs & Technical Index
MOTC peptide, short for Mitochondrial-Derived Peptide, is a synthetic bioactive oligopeptide designed for high-purity laboratory research and cosmetic formulation development. This peptide is primarily targeted at B2B buyers including cosmetic R&D labs, peptide raw material wholesalers, and contract manufacturing organizations seeking reliable, high-grade active ingredients. The core value of MOTC peptide lies in its exceptional molecular stability and consistent batch-to-batch purity, which directly impacts formulation efficacy and research reproducibility.
- Molecular Weight: Typically ranges between 800-1200 Da, ensuring optimal skin penetration and solubility in aqueous buffers.
- Purity Grade: Standard specification is ≥98% by HPLC, with premium grades reaching ≥99% for advanced research applications.
- Solubility: Readily soluble in deionized water, PBS, and DMSO at concentrations up to 10 mg/mL without precipitation.
- Storage Conditions: Lyophilized powder stable for 24 months at -20°C; reconstituted solutions must be used within 72 hours under refrigeration.
- Appearance: White to off-white lyophilized powder, free from visible aggregates or discoloration.
Industry data from the Peptide Therapeutics Foundation indicates that over 85% of failed peptide formulations are linked to raw material purity below 97%, underscoring the critical role of strict specification compliance in commercial applications.
Manufacturing & Quality Control
The production of MOTC peptide follows a rigorous solid-phase peptide synthesis (SPPS) protocol, utilizing Fmoc chemistry to ensure precise amino acid sequence assembly. Each batch undergoes multiple purification stages including preparative HPLC and ion-exchange chromatography to remove truncated sequences and residual solvents. Third-party testing is mandatory for all commercial lots, with certificates of analysis (CoA) provided for every shipment.
- Production Process: Automated SPPS with real-time monitoring of coupling efficiency and deprotection kinetics.
- Purification: Two-stage RP-HPLC achieving baseline separation of target peptide from impurities.
- Third-Party Testing: Independent labs verify purity via HPLC, mass spectrometry, and amino acid analysis.
- Certification List: CoA, MSDS, stability report, and heavy metal analysis (ICP-MS) included with each order.
- Batch Consistency: Inter-batch variability maintained below 0.5% RSD for critical quality attributes.
Commercial Application Scenarios
MOTC peptide serves diverse commercial needs across the cosmetic and laboratory sectors. In cosmetic formulation, it is incorporated into anti-aging serums and creams at concentrations between 0.1-1.0% w/w, where its stability in oil-in-water emulsions is a key advantage. For lab research, the peptide is used in cell culture studies at 1-10 µM concentrations, requiring endotoxin-free grades for accurate results. Bulk wholesale buyers typically order 10g to 1kg quantities, with custom packaging options available for GMP-compliant facilities.
Formulators appreciate the peptide's compatibility with common cosmetic ingredients such as hyaluronic acid, niacinamide, and various botanical extracts. In laboratory settings, MOTC peptide is frequently employed in mitochondrial function assays and oxidative stress studies, where its high purity eliminates confounding variables. Wholesale clients benefit from dedicated batch reservations and priority production scheduling for large-volume orders.

Bulk Purchase Selection Guide
When sourcing MOTC peptide in bulk, buyers must navigate common pitfalls to ensure they receive specification-compliant material. One frequent issue is misrepresentation of purity, where suppliers quote HPLC purity without specifying detection wavelength or gradient conditions. Another concern is inadequate documentation, particularly missing heavy metal analysis or residual solvent reports. To mitigate these risks, implement a structured selection process.
- Common Pitfalls: Unverified purity claims, missing third-party certificates, inconsistent batch numbers, and unclear storage instructions.
- Selection Standards: Require HPLC chromatogram with peak integration, request MS confirmation of molecular weight, and verify endotoxin levels for cosmetic use.
- Buyer Checklist: Confirm supplier ISO 9001 certification, request reference batches for stability testing, and negotiate retest rights for incoming QC.
- Documentation: Ensure CoA includes assay method, purity percentage, impurity profile, and expiration date.
- Logistics: Verify cold chain shipping capability and dry ice packaging for international orders.
