His-Tagged Protein Purification Protocol

Materials Required:

  • HyperSilMag-NTA beads (Ni짼✓ or Co짼✓ charged)
  • His-tagged protein sample
  • Binding buffer (50 mM NaH2PO4, 300 mM NaCl, 10 mM imidazole, pH 8.0)
  • Wash buffer (50 mM NaH2PO4, 300 mM NaCl, 20 mM imidazole, pH 8.0)
  • Elution buffer (50 mM NaH2PO4, 300 mM NaCl, 250 mM imidazole, pH 8.0)

Procedure:

  1. Equilibration: Wash NTA beads 2횞 with binding buffer.
  2. Binding: Add sample to beads. Incubate 1 hour at 4째C with gentle rotation to allow His-tag binding to Ni-NTA.
  3. Magnetic Separation: Collect beads with magnet. Remove and save flow-through.
  4. Washing: Wash 3횞 with wash buffer (20 mM imidazole) to remove non-specifically bound proteins.
  5. Elution: Add elution buffer (250 mM imidazole). Incubate 5 minutes. Collect eluate containing purified His-tagged protein.
  6. Regeneration: Wash beads with 0.5 M EDTA to strip nickel, then recharge with 50 mM NiSO4.

Capacity: >40 mg His-tagged protein per gram beads

Purity: Typically >95% in single step
