Lyophilized rGH although stable at room temperature for 3 weeks, should be stored desiccated below -18 degree C. Upon reconstitution and filter sterilization rGH can be stored at 4 degree C, pH 9 for up to 4 weeks. For long term storage and more diluted solutions it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
