Human IFN beta Recombinant Protein Lyophilized

The lyophilized IFN beta recombinant protein is stable for at least 2 years from date of receipt at -20 degree C. Reconstituted IFN beta is stable for at least 3 months when stored in working aliquots with a carrier protein at -20 degree C. As with any protein, exposing IFN beta recombinant protein to repeated freeze/thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
