Quality Control

Our Arg-Lys-Glu-Val-Tyr Acetate Salt is manufactured under controlled conditions and undergoes rigorous analytical testing to ensure identity, purity, and consistency. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing specifications such as assay by HPLC, peptide content, and related impurities. We adhere to stringent in-house quality standards suitable for research and development applications. Certificates of Analysis (COA) are available upon request.

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); allow the sealed vial to equilibrate to room temperature before opening to minimize moisture uptake. For short-term use, store desiccated at 2-8°C.
