Quality Control

Our Cik1 Protein is manufactured under stringent conditions to ensure batch-to-batch consistency and high biological activity. Each lot undergoes rigorous analytical testing, including purity assessment by SDS-PAGE and HPLC, identity confirmation, and functional activity assays. A comprehensive Certificate of Analysis (COA) detailing purity, concentration, buffer composition, and specific activity is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below in aliquots to avoid repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive) and should be handled in a dry environment. Allow the vial to reach room temperature before opening to minimize condensation.
