Quality Control

Our Plastocyanin is produced and tested under stringent conditions to ensure high biological activity and purity suitable for research applications. Each batch is characterized for its specific activity, copper content, and spectral properties (A597/A280 ratio). A comprehensive Certificate of Analysis (COA) detailing purity, activity, and physical characteristics is provided with every shipment to guarantee consistent performance and traceability.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized powder at -20°C. Reconstituted solutions should be aliquoted and stored at -80°C to prevent repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive); ensure the container is sealed in a dry environment.
