Quality Control

Our Rcsb Protein is manufactured under stringent conditions to ensure batch-to-batch consistency and high purity, meeting the exacting requirements of research and industrial applications. Each lot undergoes comprehensive analytical testing, including purity assay, identity confirmation, and activity profiling. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and compliance with your quality protocols.

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). Allow the vial to equilibrate to room temperature before opening to minimize moisture absorption. For short-term use, aliquoting is recommended to avoid repeated freeze-thaw cycles.
