USAGE
Reconstitute in sterile PBS, pH7.2-pH7.4.
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.

摘要 基因重组蛋白在大肠杆菌中表达时，由于表达量高，往往形成无生物活性的包涵体。包涵体必须经过变性和复性的过程才能获得有活性的重组蛋白。如何提高基因重组蛋白质的复性率，是生物工程技术的一个研究热点。对近年来的重组蛋白质的复性方法做一评述，为研究蛋白质折叠以及复性技术的进一步应用提供依据。 关键词 重组蛋白 包涵体 复性 二硫键 到目前为止，人们表达的重组蛋白质已有4000多种，其中用E.coli表达的蛋白质要占90%以上，尽管基因重组技术为大规模生产目标蛋白质提供
时效率最高 [2，3] 。在设计钙变色子时，用 GFP 突变体作为两个伙伴荧光团：蓝绿色荧光蛋白作为给体，而黄色荧光蛋白作为受体（见图4.1 ; 参考文献 [4])。如果两个荧光团融合于不同的作用伙伴，分子间 FRET 可以用来探测蛋白质-蛋白质相互作用，而如果两个荧光团都融合到同一个蛋白质，分子内 FRET 可用来探测蛋白质剪切和构象变化 [3] 。 4.1.2 钙变色子的一般设计 使用分子内 FRET 的概念，钙变色子由夹在 CFP 和 YFP 之间的，前后融合的 CaM 的 N
