Uniprot ACC number: Q8IZJ0
Transportation method: Shipped at room temperature.
Stability: Lyophilized IFN-Lambda 2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IFN-Lambda 2 Recombinant should be stored at +4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Solubility: It is recommended to reconstitute the lyophilized IL-28A in sterile 18MΩ-cm H
2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
