Quality Control

Every batch of our Glutamyl-Glutamyl-Glutamyl-Glutamyl-Tyrosyl-Methionyl-Prolyl-Methionyl-Glutamic Acid undergoes rigorous analytical testing to ensure it meets the stringent requirements of research and development applications. Our quality assurance protocols are designed to guarantee high purity, batch-to-batch consistency, and accurate peptide sequence confirmation. A comprehensive Certificate of Analysis (COA) detailing purity (by HPLC), identity (by MS and/or NMR), and other critical parameters is provided with each shipment to support your regulatory and quality documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. This product is hygroscopic (moisture-sensitive). Allow the vial to reach room temperature in a desiccator before opening to prevent condensation and moisture uptake. For long-term storage, consider storing under an inert atmosphere.
