这些 Ni(2+) 螯合物包被板适用于通过基于 ELISA 的方法分析多聚组氨酸标签融合蛋白。在氨基或羧基末端含有一系列多个组氨酸残基的蛋白对于金属具有强结合亲和力。含有多聚组氨酸标签融合蛋白的细菌裂解物可直接加入平板,无需封闭。透明、白色或黑色板可分别与比色、化学发光或荧光检测方法配合使用。
Thermo Scientific Pierce 镍包被白色 96 孔板可以提供一种简单的形式来结合 His 标签融合蛋白,用于 ELISA 和其他基于板的测定(涉及表达重组蛋白的蛋白相互作用)。这些白色板可与化学发光检测方法配合使用。

Pierce 镍包被板的特点:
•Ni2+ 活化表面可使 His 标签蛋白发生金属-螯合物结合
• 用于裂解细胞的去污剂不会抑制与活化板的结合,它们在使用原色聚苯乙烯时才会发生抑制
• 与其他市售镍活化板相比,针对灵敏测定具有较佳的结合能力
• 检测限:1 ng 多聚组氨酸融合蛋白
• 结合容量:约 9 pmol His 标签蛋白 (27 kDa)/孔
• 活化水平:200 µL

常见问题解答 (FAQ)

What is the binding capacity for Pierce Nickel Coated Plates?

The binding capacity for Pierce Nickel Coated Plate is approximately 9 pmol His-tagged protein (27 kDa) per well.

Why should I use ultra-pure water for washing Pierce Nickel Coated Plates?

The water used for washing of microplates as well as all assay reagents, must be of absolutely ultra-pure quality. This means that no metal ions should be present in the water, as this will bind to the His-tag and thereby decrease the binding of the fusion protein to the nickel-chelate complex.

Is it possible to elute the bound His-tagged fusion protein/peptide from the surface of Pierce Nickel Coated Plates?

Yes. For instance, use imidazole in concentrations >500 mM in Tris at pH 7.5 or a high concentration of EDTA.

With Pierce Nickel Coated Plates, can any reagent interfere with the binding between the nickel-chelate complex and the His-tagged fusion biomolecule?

Ionic detergents (e.g., SDS) will interfere with the binding as well as high concentrations of chelating reagents like EDTA, EGTA, and very strong electron donors like metal ions.

Can I use Pierce Nickel Coated Plates to measure the amount of bound His-tagged fusion protein/peptide?

To determine the approximate amount of bound His-tagged fusion protein/peptide, a standard curve of a previously purified preparation can be applied.
