The stability of the purified recombinant multimeric proteins is comparable to the stability of other recombinant proteins. These proteins are stable for at least 6 months when frozen (-70°C) or at least 7 days at 4°C. Like most recombinant proteins, excessive vortexing, dilution, and freeze-thaw should be avoided to minimize sample and activity loss. More information can be found on the datasheet.
