Manufacturing & Quality Control
The production of medicube peptide serum follows a rigorous solid-phase peptide synthesis (SPPS) process, utilizing Fmoc chemistry for precise amino acid sequence assembly. Each batch undergoes multi-stage purification to remove truncated sequences and residual solvents, ensuring pharmaceutical-grade output suitable for cosmetic and lab applications.
Production Process
Raw materials are sourced from GMP-certified suppliers, with each amino acid derivative tested for enantiomeric purity before synthesis. The SPPS process runs on automated synthesizers with real-time monitoring of coupling efficiency, followed by cleavage and deprotection under controlled acidic conditions. Crude peptides are then precipitated and dried before purification.
Purification & Analysis
Preparative reverse-phase HPLC achieves >98% purity, with each batch analyzed by analytical HPLC, mass spectrometry (MS), and amino acid analysis. Third-party testing includes endotoxin levels (<0.5 EU/mg), heavy metal screening (USP <232>), and microbial limits (USP <61>). Certifications include ISO 9001:2015 for quality management and GMP compliance for cosmetic ingredient manufacturing.
