Thermo Scientific Pierce 免疫共沉淀试剂盒提供共价抗体固定化以及进行适当控制的 co-IP 实验所需的所有组分,成品中无抗体干扰。

Co-IP 是研究蛋白:蛋白相互作用的常用方法,其使用抗体对抗原(诱饵蛋白)进行免疫沉淀,对任何相互作用蛋白(猎物蛋白)进行免疫共沉淀。使用蛋白 A 或 G 的传统 co-IP 方法可导致抗体重链和轻链的共洗脱,而这些重链和轻链可能与相关条带共迁移,掩盖了重要的结果。Pierce Co-IP 试剂盒通过将抗体共价偶联至胺反应性树脂上,解决了该问题。该试剂盒包含用于蛋白结合和回收的优化缓冲液、进行对照实验所需的试剂以及高效离心柱和收集管,可缩短方案并尽量减少操作和混合。

免疫共沉淀试剂盒的特点:

适用于任何纯化抗体—使用任何纯化抗体进行 co-IP 实验,无论物种或 Ig 类别(鸡 IgY、人 IgE、小鼠 IgG1、IgM 等)如何;不依赖蛋白 A 和蛋白 G 的亲和结合
无抗体干扰—共价结合方法和非还原洗脱系统可以产生纯 co-IP 产品,该产品不会被 IP 抗体污染
可重复使用的抗体微珠—共价抗体固定化允许重复使用制备的 IP 树脂,并可能节省昂贵抗体
全套试剂盒—所有用于抗体固定和许多 IP 实验的试剂,包括结合和洗涤缓冲液、洗脱缓冲液和便利的微量离心柱,使树脂操作更加简单和高效。
随附对照微珠—提供未衍生化琼脂糖微珠,用作非特异性结合的阴性对照
通用—co-IP 方法与任何生理(非变性)蛋白样品缓冲液兼容,缓冲液与特异性抗体抗原和蛋白相互作用复合物兼容。

免疫共沉淀 (Co-IP) 是一种用于发现蛋白相互作用的常用体外方法。Pierce 免疫共沉淀试剂盒经过配置,是有效进行 Co-IP 实验的基本工具,能够产生不含棘手的 IP 抗体的纯 IP 和 co-IP 产物。通过使用可直接且永久偶联纯 IP 抗体的 AminoLink Plus 树脂替代蛋白 A/G 琼脂糖微珠,对传统 co-IP 技术实现这种改善。温和(非还原、非变性)洗脱缓冲液可实现在保留琼脂糖微珠上固定化抗体的同时解离 IP 靶标。结果是获得一种可通过 Western 印迹(或甚至测序)进行分析的纯产物,无抗体干扰。

除消除 IP 抗体污染外,构成 Pierce Co-IP 试剂盒的抗体偶联方法还可避免传统蛋白 A 和蛋白 G 方法产生的非特异性结合相互作用和浸出污染。尽管偶联方法要求起始抗体包含在不含 BSA、明胶和其他贮藏蛋白稳定剂的无胺缓冲液中,但其不依赖于蛋白 A 或蛋白 G 这一事实意味着任何抗体种类或类别均可用于 IP(例如,IgM 和鸡 IgY)。实际上,任何纯化的蛋白都可以固定化用于结合配偶体的亲和纯化。

常见问题解答 (FAQ)

What is the shelf life of the Pierce Co-Immunoprecipitation Kit (Cat. No. 26149)?

The Pierce Co-Immunoprecipitation Kit is covered under our general 1-year warranty and is guaranteed to be fully functional for 12 months from the date of shipment, if stored as recommended (4 degrees C). Please see section 8.1 of our Terms & Conditions of Sale for more details.

Can I use samples harvested using my own Lysis Buffer with the Thermo Scientific Co-Immunoprecipitation Kit?

Yes, but the IP Lysis/Wash Buffer is formulated to be an efficient lysing agent that is gentle to proteins. The exclusion of ionic detergents and pH extremes help to preserve protein: protein interactions improving the results of recovering both antigen and its interacting partners at the elution step (versus interating partners being lost in the wash steps).

Why does the Thermo Scientific Co-Immunoprecipitation Kit include a Conditioning Buffer (100X)?

The conditioning buffer helps with the wash and especially to provide the correct environment to enhance the efficiency of the low pH Elution Buffer. The overall result is more antigen recoved in the first volume of elution (more concentrated antigen).

Can I choose to immobilize an un-purified antibody with the Thermo Scientific Co-Immunoprecipitation Kit?

No, we do not recommend immobilizing an un-purified antibody; a purified antibody is required. The AminoLink Coupling Resin that is included will react with primary amines that are found on the surface of virtually all proteins, resulting in immobilization of many other proteins along with the antibody. This will reduce the amount of antibody immobilized, resulting in less antigen and interacting partners being purified. It can also result in higher background as other proteins in the sample may bind to the other immobilized proteins and co-elute with the antigen and interacting partners, contaminating them.

The protocol recommends using 10 - 75 µg of antibody with the Thermo Scientific Co-Immunoprecipitation Kit, is it possible to use a different amount?

Yes, the product manual includes “Table 1. Amounts of antibody, coupling resin, wash buffer and elution buffer to use” that allows researchers to scale their affinity purification using 5 - 1,000 µg of antibody. We do not recommend going below 5 µg of antibody. This was the smallest amount of antibody tested inhouse. The rationale to stop at 5 µg of antibody is that it was felt that an extremely strong affinity between the antibody and antigen would be required to get sensitive, reproducible results with less antibody to capture the antigen and interacting partners.
