Quality Control

Our peptide products are manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including HPLC, MS, and NMR to confirm identity, purity, and correct sequence. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment, supporting your research and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. This product is hygroscopic (moisture-sensitive). For long-term storage, it is recommended to store desiccated under an inert atmosphere. Allow the vial to warm to room temperature before opening to minimize moisture uptake.
