The lyophilized protein is stable for at least years from date of receipt at-20 °C. Upon reconstitution, this cytokine can be stored in working aliquots at 2 degree -8 °C for one month, or at-20 °C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
