Quality Control

Our peptide products are manufactured under strict quality management systems. Each batch undergoes comprehensive analytical characterization to ensure identity, purity, and consistency. Certificates of Analysis (COA) are provided, detailing results from HPLC, MS, and amino acid analysis. We support research requiring compliance with cGMP guidelines for non-clinical materials and can provide documentation to meet rigorous institutional or regulatory standards.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. For long-term storage, consider lyophilized (freeze-dried) form kept at -20°C. The product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and hydrolysis. Store away from strong acids and bases.
