Quality Control

Our β-Lactorphin is produced and tested under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles. We adhere to relevant industry standards for research chemicals, and specifications can be tailored to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as indicated on the label or COA. The product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under recommended conditions to maintain stability and purity.
