kDa

[ STORAGE AND STABILITY ]

Storage: Avoid repeated freeze/thaw cycles.

Store at 2-8oC for one month.

Aliquot and store at -80oC for 12 months.

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.

[ SEQUENCES ]

The target protein is fused with two N-terminal Tags, His-tag and S-tag, its

sequence is listed below.
