Lyophilized Interleukin-19 although stable at room temperature for 3 weeks, should be stored desiccated below -18 degree C. Upon reconstitution IL19 should be stored at 4 degree C between 2-7 days and for future use below -18 degree C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
