简单介绍

半胱氨酸蛋白酶抑制剂2(CST2)重组蛋白蛋白质的不同在于其氨基酸的种类、数目、排列顺序和肽链空间结构的不同,蛋白质的氨基酸序列由对应基因所编码,空间结构决定于氨基酸序列本身,通过氢键或范德华力等作用力实现。蛋白质不仅具有上等结构,还具有二级、三级结构,甚至四级结构。上等结构只是蛋白质的基本结构,称之为低级结构。半胱氨酸蛋白酶抑制剂2(CST2)重组蛋白如果想让蛋白质有更多的生物功能则必须赋予它们更复杂的空间结构,称之为上等结构。应用重组DNA将目标基因进行表达得到的

    半胱氨酸蛋白酶抑制剂2(CST2)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%。

    半胱氨酸蛋白酶抑制剂2(CST2)重组蛋白[ PREPARATION ]
    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.
    [ SEQUENCES ]
    The target protein is fused with N-terminal His-tag, its sequence is listed below.
