Quality Control

Our Phe-Leu-Glu-Glu-Val Ammonium is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, MS for identity confirmation, and tests for residual solvents and heavy metals, to ensure it meets the stringent requirements for research and development. Certificates of Analysis (COA) with full traceability are provided to guarantee reproducible quality and supply reliability for your critical projects.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed in a cool, dry place and allowed to equilibrate to room temperature before opening to prevent condensation.
