[ USAGE ]

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.

[ STORAGE AND STABILITY ]

Storage:Avoid repeated freeze/thaw cycles.

Store at 2-8°C for one month.

Aliquot and store at -80°C for 12 months.

Stability Test: The thermal stability is described by the loss rate. The loss rate was determinedby accelerated thermal degradation test, that is, incubate the protein at 37°C for 48h, and noobvious degradation and precipitation were observed. The loss rate is less than 5% within theexpiration 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.
