  大肠杆菌宿主残留蛋白(ECP)重组蛋白用法

  PBS或其它。

  储存

  避免反复冻融。2-8°C不超过一个月，-80°C不超过12个月。

  稳定性

  热稳定性以损失率显示。损失率是由加速降解试验决定，具体方法如下：在37°C孵育48小时，没有显著的降解或者沉淀产生。保质期内，在适当的条件下存储，损失率低于5%。大肠杆菌宿主残留蛋白(ECP)重组蛋白

  Store at 2-8oC for one month.
  Aliquot and store at -80oC for 12 months.大肠杆菌宿主残留蛋白(ECP)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 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 T7-tag, its
  sequence is listed below.
