Quality Control

Our Lactoferrin (318-323) is produced under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity, MS for identity confirmation, and amino acid analysis. We provide Certificates of Analysis (COA) with each shipment, detailing all specifications. Production can adhere to cGMP guidelines for research and commercial applications.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent moisture absorption. For short-term use, store at 2-8°C.
