Quality Control

Our Peptide Ii (Aplysia) is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability for sensitive research applications. Each lot is subjected to rigorous analytical testing, including purity assessment by HPLC and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your research documentation and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. Due to its hygroscopic (moisture-sensitive) nature, the product should be allowed to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. For long-term stability, store under inert atmosphere if the container is repeatedly accessed.
