[ USAGE ]

Reconstitute in sterile ddH2O.

[ STORAGE AND STABILITY ]

Storage: Avoid repeated freeze/thaw cycles.

?Store at 2-8

oC for one month.

?Aliquot and store at -80oC for 12 months.

Stability Test: The thermal stability is described by the loss rate of the targetprotein. The loss rate was determined by accelerated thermal degradation test,that is, incubate the protein at 37oC for 48h, and no obvious degradation andprecipitation were observed. (Referring from China Biological Products Standard,which was calculated by the Arrhenius equation.) The loss of this protein is lessthan 5% within the expiration date under appropriate storage condition.
