Store at 2-8oC for one month. Aliquot and store at -80oC for 12 months . Stability Stability Stability Stability Test: The thermal stability is described by the loss rate of the target protein. The loss rate was

determined by accelerated thermal degradation test, that is, incubate the protein at 37oC for 48h, and no obvious

degradation and precipitation were observed. (Referring from China Biological Products Standard, which was

calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under

appropriate storage condition.
