Liquid or Lyophilized powder缓冲液:
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.储存条件:
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.保质期:
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.货期:
3-7 business days注意事项:
Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.功能1:
Antagonist of fibroblast growth factor (FGF) pathways via inhibition of FGF-mediated phosphorylation of ERK1/2 . Thereby acts as an antagonist of FGF-induced retinal lens fiber differentiation, may inhibit limb bud outgrowth and may negatively modulate respiratory organogenesis . Inhibits TGFB-induced epithelial-to-mesenchymal transition in retinal lens epithelial cells . Inhibits CBL/C-CBL-mediated EGFR ubiquitination .功能2:

文献和实验【原创】Protein A Sepharose 之进化篇。。。
洗脱条件比较剧烈,最后收集的蛋白质很有可能变性,或者是复性困难。 这种洗脱条件剧烈的Protein A 柱结合的重组蛋白质A一般具有5个串联结构域:E、D、A、B、C。这种重组蛋白A虽然除去了不重要的非结合域,仅由5个结构域组成,每个域均可以和IgG的Fc段结合,但不同的域结合强度略有差异。因此洗脱条件不均一,而且经常需要较低的pH值。如果减少串联结构域的个数,并且采取同型结构域串联,就可以避免不同结构域与抗体Fc 段亲和性的差异,洗脱条件会温和而均一。为此,我们可以做一个试验,比较一下
也可以从其他物种中去除白蛋白。适用于处理 25 或 50 个样本。Figure 1: 2D analysis of whole human serum before (left) and after(right) treatment with AlbminOUT™. 产品特点: ● 从样本中不到 10 分钟的时间内去除白蛋白 ● 基于白蛋白和 Cibachron 蓝色染料的结合 ● 每个柱子的结合力大于 2 mg 的人白蛋白 ● 从 5-50
肝炎病毒包膜E2蛋白相同的亲和结合力3。另外,有阴离子转运载体AE1结构域的重组蛋白被标记且用Rho1D4系统纯化后表现出与红细胞来源的AE1蛋白有相同的硫酸外排速率。4) 利用Rho1D4纯化膜蛋白图解简述步骤1:结合:将Rho1D4标记的蛋白与载有Rho1D4抗体的琼脂糖一同孵育使得目标蛋白被固定在吸附材料上。 步骤2:清洗:将杂蛋白和其他裂解液成分洗去,留下与亲和基质结合的目标蛋白。 步骤3:洗脱:过量Rho1D4肽与基质竞争性结合,释放出目标蛋白在洗脱液中收集。 表
