Quality Control

Our β-Interferon is manufactured under strict quality systems suitable for research and pharmaceutical applications. Each batch is subjected to a comprehensive battery of analytical tests to ensure identity, purity, potency, and safety. We provide full traceability and support regulatory filings. Certificates of Analysis (COA) detailing specifications such as purity (by HPLC), biological activity (by cell-based bioassay), endotoxin levels, and sterility are available upon request.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized material at -20°C or below. Reconstituted solutions should be aliquoted and stored at -70°C to -80°C to prevent loss of activity. Avoid repeated freeze-thaw cycles. This product is hygroscopic (moisture-sensitive).
