How do you reuse Ni-NTA beads?

by

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 you regenerate Ni-NTA beads?

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 clean Ni-NTA beads?

Rinse the detergent with ethanol 70% (approximately 10 column volumes). 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.

How do I recharge my HisTrap column?

Re-charge the water-washed column by loading 0.5 ml or 2.5 ml of 0.1 M NiSO4 in distilled water on HisTrap HP 1 ml and 5 ml column, respectively. Salts of other metals, chlorides or sulfates, may also be used (see Optimization).

How do you reuse Ni-NTA column?

What is Ni-NTA resin?

Ni-NTA Agarose is a nickel-charged affinity resin that can be used to purify recombinant proteins containing a polyhistidine (6xHis) sequence. … Ni-NTA uses the chelating ligand nitrilotriacetic acid (NTA) coupled to a cross-linked 6% agarose resin that is suitable for use in batch and gravity flow applications.

How do you reuse Ni-NTA resin?

How do you recharge nickel resin?

  1. Use the same resin for the same protein purification.
  2. You can wash the Ni resin with 0.5N NaOH 30min for rapid regeneration if the resin is still light blue.
  3. Reuse of Ni resin: A maximum of 5 runs per column is recommended.
  4. Ni-NTA matrices should be stored in 20% ethanol to inhibit microbial growth.
