Human IFN-beta Recombinant Protein (Animal Free) Lyophilized

The recombinant protein is stable for at least 2 years from date of receipt at -20 degree C. Reconstituted protein 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 the 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.
