Quality Control

Our Interferon Alphab is manufactured and tested under strict quality management systems. Each batch is subjected to a comprehensive suite of analytical tests to ensure identity, purity, potency, and safety, meeting the stringent requirements for research and pharmaceutical applications. A detailed Certificate of Analysis (COA) documenting purity (by HPLC), specific activity (in IU/mg), endotoxin levels, and sterility is provided with every shipment.

Storage

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