Quality Control

Every batch of H(-Asn-Pro-Asn-Ala)6-Oh is manufactured under controlled conditions and undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our quality assurance protocol is designed to meet the exacting standards of research and development. A comprehensive Certificate of Analysis (COA) detailing purity (by HPLC), molecular weight confirmation (by MS), and other critical parameters is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. For long-term storage, consider desiccation or storage under an inert atmosphere to minimize degradation, as the product is hygroscopic (moisture-sensitive). Allow the sealed vial to equilibrate to room temperature before opening to prevent condensation.
