Described herein is a storage medium for transport of NK-92 cells comprising human serum, about 200 IU/mL and a density of non-irradiated NK-92 cells sufficient to provide a therapeutic amount of NK-92 cells at the time of delivery to a treatment facility, wherein the temperature of the medium is maintained within +/−5° C. of a selected temperature between 20° C. and 40° C., such that the NK-92 cells remain viable for administration to a patient for up to a period of at least 24 hours after placement into the storage medium. Also described are methods of transporting NK-92 cells such that the NK-92 cells remain viable for administration to a patient for up to a period of at least 24 hours after placement into the storage medium.
