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.

文献和实验Characterization of Epithelial Cells in the Hair Follicle With S100 Proteins
proteins are expressed in very restricted regions of the hair follicle: S100A3 and S100A6 in distinct postmitotic differentiated epithelial cells and S100A4 and S100A6 in the epithelial stem cell compartments. Characterization of epithelial cells
较少。研究者使用激光显微切割技术富集正常细胞和癌变的胰腺导管上皮细胞。从分离下来的细胞中分别提取蛋白，然后通过二维电泳进行分离。对二维电泳分离得到的蛋白进行银染以进行观察。当然，跑胶时确保使用相同的蛋白上样量非常关键。对比正常的和癌变的胰腺上皮细胞的蛋白图谱，发现其中九个蛋白点表达有差异。其中五个蛋白在肿瘤细胞中上调，而其中四个下调。其中一个在肿瘤细胞中表达增强的蛋白，被确定为钙结合蛋白，S100A6。 为了确定S100A6的过表达对胰腺癌的影响，我们使用了来自46个胰腺癌患者的174个重复点
这些差异可将蛋白从混合物如大肠杆菌裂解物中提取出来得到重组蛋白。蛋白的纯化大致分为粗分离阶段和精细纯化阶段二个阶段。粗分离阶段主要将目的蛋白和其他细胞成分如DNA、RNA等分开，由于此时样本体积大、成分杂，要求所用的树脂高容量、高流速，颗粒大、粒径分布宽.并可以迅速将蛋白与污染物分开，防止目的蛋白被降解。精细纯化阶段则需要更高的分辨率，此阶段是要把目的蛋白与那些大小及理化性质接近的蛋白区分开来，要用更小的树脂颗粒以提高分辨率，常用离子交换柱和疏水柱，应用时要综合考虑树脂的选择性和柱效两个因素。选择性指
