Quality Control

Our Phycoerythrobilin is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity suitable for research applications. Each lot is characterized using advanced analytical techniques including HPLC, UV-Vis, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and related substance profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation. Allow the sealed vial to equilibrate to room temperature before opening to prevent condensation and moisture uptake.
