Quality Control

Our Recombinant Pf4-241 is manufactured under stringent conditions to ensure the highest standards of purity and biological activity. Each batch undergoes comprehensive analytical testing, including identity confirmation, purity assessment, and functional activity assays. Certificates of Analysis (COA) detailing purity, endotoxin levels, and biological activity are available upon request to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below. Avoid repeated freeze-thaw cycles. Due to its hygroscopic (moisture-sensitive) nature, the product should be handled in a dry environment and allowed to equilibrate to room temperature before opening to prevent condensation.
