ProBond™ 镍螯合树脂

ProBond™ 镍螯合树脂是一种镍荷电亲和树脂，用于纯化含多聚组氨酸 (6xHis) 序列的重组蛋白。与树脂结合的蛋白可使用低 pH 值缓冲液或通过与咪唑或组氨酸竞争进行洗脱。在天然和变性条件下均可进行一步纯化。ProBond™ 树脂使用螯合配体亚氨基二乙酸了解更多信息

常见问题解答 (FAQ)

你们通常怎样检测重组融合蛋白的表达？

通常使用免疫印迹分析法检测蛋白表达。我们提供许多针对不同表位的抗体，如Xpress、HisG、V5或C-端6xHis。此外，可以用我们的ProBond亲和纯化系统来纯化His标签蛋白。

How do you typically detect expression of a recombinant fusion protein?

Western blot analysis is typically used to detect the expressed protein. We sell several antibodies against various epitopes, such as Xpress, HisG, V5, or C-terminal 6xHis. Additionally, His-tagged proteins can be purified using our ProBond Purification System via affinity purification.

What expression levels can be expected with the pTrcHis/CAT construct?

In one experiment, 35 µg CAT/mg total protein or 68.2 mg CAT/liter of culture was obtained. 50 ml of cell extract was loaded onto a ProBond column and 2 mg of CAT was recovered. The eluted protein appeared reasonably pure on a gel.

I purified my protein from a ProBond column using denaturing conditions. After elution, I tried digesting off my N- terminal tag with EKMax Enterokinase, but see no EK cleavage. What can you suggest I try?

The enzyme could be denatured. Try buffer exchange or dialysis before digestion with EKMax Enterokinase.

Can ProBond or Ni-NTA beads be used for large-scale preparations?

ProBond and Ni-NTA beads can be used in FPLC columns. However, the beads can only withstand low pressure (~43.5 psi max).
