Product Details

Ni-NTA Superflow 是用于纯化 His 标记蛋白的最常用树脂,有预装 1 ml 和 5 ml 试剂盒可供选择,用于在 FPLC、ÄkTA 和 BioLogic 等液相色谱系统上进行自动纯化,或使用注射器手动纯化。

Performance

Ni-NTA 在提供高产量的高纯度蛋白方面的性能优于其他树脂(见图  Ni-NTA 在提供高产量的高纯度蛋白方面优于其他树脂)。与其他市售镍树脂进行的独立比较表明,Ni-NTA Superflow 的镍浸出水平最低(见图 一项独立研究表明,Ni-NTA 比其他任何测试过的树脂损失的镍都要少)。其意义在于,如果镍从树脂中浸出,剩余的带电配体就会充当离子交换剂,与无标记蛋白结合,从而污染洗脱馏分。Ni-NTA 具有较高的稳定性,这意味着即使在 10 mM DTT 存在的情况下,也可使用其获得完全活性的高纯度蛋白(见图 与 IDA相比,Ni-NTA 中的额外配位点与镍结合得更紧密)。

如表中所示,在所有纯化规模中,纯度始终保持在较高水平。Ni-NTA Superflow Cartridges 是 QIAGEN 提供的 His 标记蛋白综合互补解决方案的一部分(见图 对纳克到克级的 His 标记蛋白进行可扩展纯化)。

Principle

Ni-NTA 基质是纯化 His 标记蛋白的首选亲和层析溶液(见图 一步法高效纯化 His 标记蛋白)。它们非常稳定,这意味着它们能与多种缓冲液成分兼容,包括强变性剂、洗涤剂甚至还原剂(见表“与 His/Ni-NTA 相互作用兼容的试剂”)。这种灵活性使研究人员能够开发出最佳的纯化方案,同时还能受益于 Ni-NTA 带来的出色分离特性,这种特性通常使第二个层析步骤成为多余步骤。

Procedure

耐用的 Superflow 基质允许的流速高达 10 ml/min(1 ml 试剂盒)和 40 ml/min(5 ml 试剂盒),从而能够加快纯化过程并提高产量。试剂盒可快速、方便地连接到液相色谱系统,或连接到注射器进行手动纯化。纯化过程可重现性高,可确保每次都能制备出同样优质的蛋白(见图 可重现性和可靠性高的纯化)。

Applications

Ni-NTA 基质可用于扩大用于结构研究(例如使用蛋白质晶体学或 NMR 的研究)的 His 标记蛋白的纯化规模,或用于克级产量的生物制药生产。

FAQ

Can the Ni-NTA Superflow Cartridges and/or Strep-Tactin Cartridges be connected in series?

Yes, Ni-NTA and Strep-Tactin Superflow Cartridges can be connected in series.

The Union M6 female/1/16’’ male connector from GE (Code No. 18-3858-01) can be used for this, for example.

 

FAQ ID -1606
How fast is the 6xHis-tagged protein purification process using Ni-NTA Superflow Cartridges?

A maximum of 1 hour is needed for the complete purification process with Ni-NTA Superflow Cartridges when recommended flow rates are applied. This is true for 1 ml and 5 ml cartridges.

Details for a typical 1 ml column run:

  • Equilibration (5 column volumes (cv)): 5 min
  • Load (10 ml Cleared Lysate): 10 min
  • Wash (10 cv): 10 min
  • Elution (10 cv): 10 min
  • optional: Cleaning-in-place (0.5 M NaOH, 0.5 ml/min, 7.5 cv): 15 min  
FAQ ID -1605
What is the binding capacity of the Ni-NTA Superflow Cartridges?

The binding capacity of Ni-NTA resins is protein dependent. We guarantee a binding capacity of up to 20 mg/ml of Ni-NTA Superflow for every 6xHis-tagged protein (up to 20 mg per 1 ml Ni-NTA Superflow Cartridge).

However, we have examples where the binding capacity is higher (e.g.: 6xHis-CAT: 30 mg/ml resin; 6xHis-GFP: 55 mg/ml resin).

  • Binding capacity for the 1 ml Ni-NTA Superflow Cartridge: 20 mg
  • Binding capacity for the 5 ml Ni-NTA Superflow Cartridge: 100 mg

 

FAQ ID -1603
Can the Ni-NTA and Strep-Tactin Superflow Cartridges be reused?

If the same protein is purified, the Ni-NTA and Strep-Tactin Superflow Cartridges can be used more than once. Cleaning in place (CIP) is recommended between purifications (0.5 M NaOH, 0.5 ml/min, 7.5 cv for 15 min).

However, for sequential purification of different proteins we recommend to use different cartridges. Please note that cartridges cannot be opened!
