Quality Control

Our Preproenkephalin is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability for research purposes. Each lot undergoes comprehensive analytical testing, including purity assessment by HPLC and identity confirmation. A detailed Certificate of Analysis (COA) documenting all relevant specifications is provided with every shipment and is available upon request.

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) and should be kept under desiccated conditions. Allow the sealed container to reach room temperature before opening to minimize moisture uptake.
