Quality Control

Our Oxygen-Evolving Complex, 23 Kda Protein is produced and handled under stringent conditions to ensure batch-to-batch consistency and high biological activity. Each lot undergoes comprehensive analytical testing, including purity assessment via SDS-PAGE and HPLC, and functional activity assays. Certificates of Analysis (COA) detailing specific results are available upon request to support your research and quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below. This product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. Aliquot into single-use vials after thawing to avoid repeated freeze-thaw cycles.
