USAGE
Reconstitute in sterile PBS, pH7.2-pH7.4.
STORAGE AND STABILITY
碳酸酐酶ⅤA(CA5A)重组蛋白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.

条件下较高的本底表达，为了让表达系统严谨调控产物表达，能过量表达lacI阻遏蛋白的lacIq 突变菌株常被选为Lac/Tac/trc表达系统的表达菌株。现在的Lac/Tac/trc载体上通常还带有lacIq 基因，以表达更多lacI阻遏蛋白实现严谨的诱导调控。IPTG广泛用于诱导表达系统，但是IPTG有一定毒性，有人认为在制备医疗目的的重组蛋白并不合适，因而也有用乳糖代替IPTG作为诱导物的研究。另外一种研究方向是用lacI的温度敏感突变体，30度下抑制转录，42度开发。热诱导不用添加外来的诱导物，成本
