Quality Control

Our synthetic peptides are manufactured under strict quality control protocols to ensure identity, purity, and batch-to-batch consistency. Each lot is characterized using advanced analytical techniques including HPLC for purity assessment and Mass Spectrometry (MS) for confirmation of molecular weight and sequence. A comprehensive Certificate of Analysis (COA) detailing all test results 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. This product is hygroscopic (moisture-sensitive). For long-term storage, it is recommended to store desiccated. Allow the vial to warm to room temperature in a desiccator before opening to prevent condensation and hydrolysis.
