Quality Control

Our high-purity peptide products are manufactured under strict quality management systems. Each batch undergoes comprehensive analytical characterization using techniques including HPLC, MS, and NMR to confirm identity, purity, and sequence integrity. We provide full traceability and Certificates of Analysis (COA) are available upon request, detailing all relevant specifications to support your research and regulatory documentation needs.

Storage

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