Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. For research-grade peptides like L-Lysine, L-Lysyl-L-Lysyl-L-Lysyl-L-Lysyl-L-Lysyl-, quality is assured through analytical methods including HPLC for purity and MS for sequence confirmation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container should be kept in a desiccated environment. For long-term stability, consider storage at -20°C.
