/Form
Liquid or Lyophilized powderBuffer
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.Reconstitution
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.Storage
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℃.Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.Relevance
Troponin T is the tropomyosin-binding subunit of troponin, the thin filament regulatory complex which confers calcium-sensitivity to striated muscle actomyosin ATPase activity.Function

文献和实验总蛋白(包括质膜和细胞器膜蛋白),但费时费力。目前,有一种最新型有效的膜蛋白提取工具,并具有高纯度、高特异性、高载量温和提取的优点。是基于1980年科学家在牛眼视网膜中发现的一种命名为Rho1D4的氨基酸序列以及其对应的抗体来作为亲和标签纯化膜蛋白取得了非常好的效果,将Rho1D4抗体链接在琼脂糖或磁珠上,用于亲和层析带有Rho1D4标签的膜蛋白,能近乎完美的解决这些研究难题。1) 什么是Rho1D4?Rho1D4是指在牛眼视网膜细胞内的牛视紫红质C端的最后九位氨基酸。Rho1D4得名于与该序列
-100mM 2-BME或DTT,也有文献使用5mM浓度。在较粗放的条件下,可以使用5ml/l的浓度。还原剂的使用浓度与蛋白二硫键的数目无关,而有些没有二硫键的蛋白加不加还原剂无影响,如牛生长激素包涵体的增溶。对于目标蛋白没有二硫键某些包涵体的增溶,有时还原剂的使用也是必要的,可能由于含二硫键的杂蛋白影响了包涵体的溶解。[4] 二、复性: 由于包涵体中的重组蛋白缺乏生物学活性,加上剧烈的处理条件,使蛋白的高级结构破坏,因此重组蛋白的复性特别必要。 通过缓慢去除变性剂使目标蛋白从变性
