How does NI-NTA purification work?

How does NI-NTA purification 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.

How do you reuse Ni-NTA column?

The reuse of Ni-NTA Agarose and Ni-NTA Superflow resins depends on the nature of the sample and should only be performed with identical recombinant proteins. We recommend a maximum of 5 runs per column. After use the resin should be washed for 30 minutes with 0.5 M NaOH.

How do I clean my Ni-NTA column?

For Qiagen’s Ni-NTA, a simple regeneration protocol is:

  1. Wash with water.
  2. Remove Ni2+ ions with 50 mM EDTA.
  3. Wash with water.
  4. Clean with 0.5 M NaOH.
  5. Neutralise with water (this will take some time)
  6. Regenerate with 100 mM NiSO.
  7. Wash with water and then either 20% ethanol or buffer.

How do you regenerate Ni NTA resin?

How do you reuse Ni-NTA resin?

How do I recharge a Ni-NTA column?

Wash the resin with 10 column volumes of distilled water to rinse out the ethanol. To recharge the agarose with Ni2+, wash with five volumes 0.1M NiSO4 x 6 H20. Wash and remove excess metal ions with five volumes of deionized water. Prepare the column by adding 5 column volumes of the binding buffer.

What is a chemical compatibility chart?

This Chemical Compatibility Chart is a shorthand tool for describing the suitability of miniature fluidic and pneumatic component materials for use in contact with various chemicals. Use this chart to help guide your component selection.

What is in the Ni-NTA purification system with antibody?

The Ni-NTA Purification System with Antibody includes resin, reagents, and columns as described for the Ni-NTA Purification System and 50 μL of the appropriate purified mouse monoclonal antibody. Sufficient reagents are included to perform six purifications and 25 Western blots with the antibody.

Why is chemical compatibility of component parts so important?

Chemical compatibility of component parts is extremely important because of possible rapid degradation and failure if the materials are not compatible with the environment where they are used or the chemical they are in contact with.
