Quality Control

Every batch of n-Palmitoyl-Seryl-Seryl-Asparaginyl-Alanine is manufactured under controlled conditions and undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our quality assurance protocols are designed to meet the stringent requirements of research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity (by HPLC), identity confirmation (by MS and NMR), 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 for long-term stability. This product is hygroscopic (moisture-sensitive); allow the sealed vial to equilibrate to room temperature before opening to minimize condensation and moisture uptake. For short-term use, store desiccated at 2-8°C.
