How does Ni-NTA column work?
NTA occupies four of six ligand binding sites of the nickel ion, leav- ing two sites free for interaction with the His6-tag. NTA binds metal ions tightly, allowing use of stringent washes. Histidine residues on the tag, connected via a short linker to the C- or N-terminus of the protein, bind to the Ni-ions.
What is NTA free?

How do you regenerate a Ni-NTA column?
For Qiagen’s Ni-NTA, a simple regeneration protocol is:
- Wash with water.
- Remove Ni2+ ions with 50 mM EDTA.
- Wash with water.
- Clean with 0.5 M NaOH.
- Neutralise with water (this will take some time)
- Regenerate with 100 mM NiSO.
- Wash with water and then either 20% ethanol or buffer.
How do I create a Ni-NTA column?
