Quality Control

Our L-Aspartic Acid, L-Arginyl-L-Arginyl-L-Arginyl-L-α-Aspartyl-L-α-Aspartyl-L-α-Aspartyl-L-Seryl-L-α-Aspartyl-L-α-Aspartyl- is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and development applications. Certificates of Analysis (COA) detailing purity, sequence verification (by MS), and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider desiccants or inert atmosphere.
