Storage & Handling
−| Storage | The lyophilized FGF-4 recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted FGF-4 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing FGF-4 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. |
