Quality Control

This high-value peptide is manufactured under strict cGMP-like conditions to ensure batch-to-batch consistency and traceability. Quality is verified through a comprehensive suite of analytical techniques including HPLC for purity, mass spectrometry (MS) for identity confirmation, and amino acid analysis (AAA). A detailed Certificate of Analysis (COA) is provided with each shipment, documenting purity, peptide content, and solvent residues. Our quality system is designed to meet the stringent requirements of pharmaceutical research and preclinical development.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. For extended storage under inert atmosphere, please contact our technical team for specific recommendations.
