Quality Control

Our synthetic peptides are manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including HPLC for purity assessment and Mass Spectrometry (MS) for identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and other critical parameters is provided with every shipment to support 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. For long-term storage, lyophilized powder is recommended. The product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature before opening to minimize moisture absorption. Store under inert atmosphere if specified.
