Quality Control

Our Cytochrome B557 is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and biological activity, meeting the high standards required for research and diagnostic applications. Certificates of Analysis (COA) detailing specifications such as purity (by HPLC), specific activity, and spectral properties 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 product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture. For short-term use, aliquoting is recommended to avoid repeated freeze-thaw cycles.
