Reconstitute in sterile PBS, pH7.2-pH7.4.

Storage: Avoid repeated freeze/thaw cycles. Store at 2-8^oC for one month. Aliquot and store at -80^oC for 12 months.
蛋白激酶R(PKR)重组蛋白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 37^oC 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.
